Introduction to Magnetic Hoops
If you have ever engaged in the "plastic hoop wrestling match"—tightening the screw until your fingers ache, tugging the fabric, re-tightening, and still finding the tension uneven—this walkthrough is your ceasefire agreement.
In this guide, based on an unboxing of Sewtal magnetic hoops (similar to the high-performance magnetic frames offered by SEWTECH), we move beyond simple product features. As an embroidery specialist, I treat this not just as a "new tool" but as a fundamental shift in your production physics. We will explore two popular sizes (18×13 cm and 26×16 cm) and decode why switching from mechanical friction (screws) to magnetic force creates a safer, faster, and more professional workflow.
You are about to learn how to perform a "Pre-Flight Inspection" on these tools, how to verify compatibility with data-driven precision, and how to harness magnetic clamping to handle fabrics that usually make embroiders cry—like thick felt or delicate velvet.

What you’ll learn (and what this post is not)
- The "Unboxing Protocol": How to inspect magnets for safety and integrity immediately upon arrival.
- Sizing Strategy: How to map the 18×13 cm and 26×16 cm dimensions to your actual design needs.
- The Physics of Quality: Why magnetic clamping eliminates "hoop burn" (the permanent crushing of fabric fibers).
- The "Impossible" Materials: How to easily hoop thick felt (pannolenci) that physically cannot fit in standard plastic frames.
This is a technical deep dive into the workflow of magnetic hooping. Whether you use a Brother, Janome, or a commercial multi-needle machine, the principles of physics and preparation remain the same.
Why Use Magnetic Hoops?
The core value proposition here is Non-Destructive Holding. A traditional plastic hoop works by jamming fabric into a groove and locking it with a screw. This creates friction and compression. A magnetic hoop works by sandwiching the fabric between two flat surfaces using vertical magnetic force. This difference saves your garments and your wrists.

Eliminating hoop marks: what’s really happening
The creator explains that magnetic hoops don't leave those "ugly marks." Let's break down the science of Why.
"Hoop burn" is caused by Compression + Friction + Time. When you force fabric into a plastic ridge, you are essentially crushing the fibers. On delicate materials like velvet, corduroy, or performance knits, this damage is often permanent.
The Magnetic Advantage:
- Zero Shear Force: You aren't dragging the fabric into a groove; you are placing a clamp on top of it.
- Distributed Pressure: The magnets effectively clamp the entire perimeter with equal force, rather than concentrating stress near the screw mechanism.
If you are tired of steaming garments for 20 minutes to remove rings, or if you are ruining high-end blanks, magnetic embroidery hoops are the calculated solution to upgrade your finish quality without changing your machine.
Speed and efficiency in hooping (where the time actually goes)
The video highlights the time saved by not tightening screws. But purely from a production management perspective, the real time-saver is Repeatability.
In a commercial timeline, "hooping time" isn't just the clamping. It represents:
- Loosening the screw (5s).
- Aligning fabric (15s).
- Tightening the screw (10s).
- The Failure Loop: Realizing it's puckered -> Loosening -> Re-tightening (30s+).
Magnetic hoops cut this loop. Snap on, smooth out, stitch. If you are doing a run of 50 left-chest logos, saving 45 seconds per shirt equals nearly 40 minutes of gained production time. This is the difference between a hobby and a profitable business.
Warning: Blade Safety. When opening shipping boxes containing magnetic hoops, keep utility knives shallow. Scratching the smooth surface of the hoop frame can create burrs that will snag delicate fabrics later (like satin or silk).
Hooping Thick Materials Made Easy
This is the specific pain point where magnetic hoops virtually pay for themselves. The creator notes they are "very useful" for thick felt. In my experience, for materials thicker than 2-3mm, standard plastic hoops are statistically likely to fail (pop open) mid-stitch.

Challenges with standard plastic frames
Plastic hoops have a physical limit: the "throat" of the groove. If you force a thick towel or heavy wool felt into it:
- Recoil: The hoop wants to spring open.
- Shadowing: The fabric bulges in the center, changing the distance to the needle plate, which causes skipped stitches or loop-outs.
The magnetic solution for felt and towels
With magnets, you are not fighting the thickness. You are clamping the perimeter.
The Sensory Check: When hooping thick felt with magnets, you should hear a solid thud or snap. This auditory feedback confirms the magnetic flux has engaged through the material. If the magnets slide around easily, the material is too thick (likely over 5mm/0.2 inches) and you may need stronger industrial magnets or a sticky stabilizer "float" method instead.
However, for standard crafts, tote bags, and towels, how to use magnetic embroidery hoop techniques turn a struggle into a simple "place and stick" action.
Included Accessories
A professional embroidery setup requires precision. The box includes the hoops, a manual, and the critical Alignment Grid (often called a template or "dima").

Using the alignment grid (Dima)
Most beginners throw this plastic sheet away. Do not do that. It is your primary navigation tool.
Action Plan:
- Mark Your Fabric: Use a water-soluble pen or chalk to mark the crosshair center on your fabric.
- Hoop blindly: Place the fabric on the magnetic base.
- Verify: Drop the transparent grid into the inner frame.
- Adjust: If the grid's crosshair doesn't match your chalk mark, simply lift the magnet, slide the fabric, and snap it back down.
This "micro-adjustment" capability is impossible with screw hoops (where you'd have to unscrew everything). For users aiming for perfect placement on polos or pockets, combining this grid with a magnetic hooping station is the gold standard for consistency.
Hoop sizes: 18×13 and 26×16
The video displays two versatile sizes:
- 18×13 cm (approx. 5x7 inch): The workhorse. Perfect for left-chest logos, onesies, and standard greeting card designs.
- 26×16 cm (approx. 10x6 inch): The production booster. Ideal for larger jacket backs (on smaller scales) or "multi-hooping" (setting up two small designs in one run).

Expert Rule of Thumb: Always use the smallest hoop that fits your design.
- Why? Less excess fabric = "drum-tight" tension.
- Why? Less physical weight on the machine's pantograph arm = better registration and motor longevity.


Compatibility
This is the "Pre-Flight Check" that saves you return shipping fees. Magnetic hoops are not universal; the attachment bracket must match your specific machine's arm width and locking mechanism.

Fitting Brother embroidery machines
The creator uses a Brother machine. Whether you use a Brother, Babylock, or Bernina, the connection point is the variable.
The Checklist for Compatibility:
- Measure the Arm Width: Use calipers or a ruler. Is your machine's connection arm 30mm? 40mm?
- Check the Clip Style: Does it slide in and click? Does it screw on?
- Verify Max Field: Your machine has a software limit. You cannot use a 300x200 hoop on a machine limited to 100x100 embroidery area—the carriage will crash.
When searching for magnetic embroidery hoops for brother, cross-reference your specific model number (e.g., "SE1900", "PE800", "PR1055X") with the SEWTECH or brand compatibility chart.
Finding the right size for your model
Strategic Advice:
- Level 1 (Hobby): If you are fighting hoop burn on a single-needle home machine, a 5x7 magnetic frame is the single best investment to improve quality.
- Level 2 (Business): If you are running production (30+ items/day), consider that magnetic hoops also reduce wrist strain (Carpal Tunnel is a real risk in this industry).
- Level 3 (Scaling): If you optimize your hooping but the machine is still too slow (single needle thread changes), the next logical step is upgrading to a multi-needle machine (like SEWTECH's commercial lines) to match your new hooping speed.
Conclusion
The verdict is clear: The build quality (solid metal frame), the clamping strength, and the workflow speed make this an essential upgrade for anyone serious about embroidery.

Is the upgrade worth it?
Yes, if you meet these criteria:
- The "Velvet Test": You embroider napped fabrics (towels, velvet) and hate the "crushed ring" look.
- The "Felt Flight": You embroider stiff/thick materials that pop out of plastic hoops.
- The "Wrist Factor": You have physical limitations or pain from repetitive screw tightening.
Where to buy (and how to buy safely)
When purchasing, don't just buy "a magnetic hoop." Buy a solution.
The Upgrade Path:
- Problem: "I can't hoop this thick hoodie." -> Solution: SEWTECH Magnetic Hoop (Strong Force).
- Problem: "I am spending 5 minutes hooping per shirt." -> Solution: Magnetic Hoop + Hooping Station.
- Problem: "My hoop marks are permanent." -> Solution: Magnetic Frames (Flat clamping).
For industrial users, look for terms like magnetic embroidery frames which often refer to the high-durability versions compatible with Tajima, Barudan, or SEWTECH multi-needle machines.
Primer (Quick Start Summary)
Do not rush to the machine. Follow this sequence to establish a baseline of safety.
- Unbox on a clear table (magnets can snatch scissors from inches away).
- Inspect surface: Run your finger along the inner edge. It must be perfectly smooth.
- Verify Magnets: Ensure all magnets are present and seated securely.
- Dry Run: Practice the "slide-off" technique (sliding magnets off rather than pulling straight up) to save finger strength.

Prep
Amateurs focus on the stitching; professionals focus on the Prep. 80% of embroidery failures happen before the start button is pressed.
Hidden consumables & prep checks (the stuff people forget)
To succeed with magnetic hoops, you need:
- Temporary Spray Adhesive (e.g., 505): Crucial for magnetic hooping. Since you aren't "jamming" the fabric, a light mist helps the fabric stick to the stabilizer, preventing "micro-shifting."
-
The Right Needle:
- Knits: Ballpoint (75/11).
- Woven/Felt: Sharp (75/11 or 90/14 for thick felt).
- Double-check: Is your bobbin full? Running out of bobbin thread on a thick felt project is a nightmare to restart.
Stabilizer decision tree (fabric → backing)
The magnet holds the perimeter; the stabilizer holds the center.
Decision Tree:
-
Is the fabric stretchy (T-shirt, Hoodie, Performance Wear)?
- MUST USE: Cutaway Stabilizer. (Tearaway will result in a distorted design).
- Hooping: Don't stretch the fabric! Lay it gentle and flat.
-
Is the fabric stable/thick (Felt, Denim, Canvas)?
- OPTION: Tearaway Stabilizer is usually fine.
- Heavier: If the stitch count is high (10,000+ stitches), use a medium-weight Cutaway for support.
-
Is the fabric napped/fluffy (Towel, Velvet)?
- ADDITION: You need a Water Soluble Topper (Solvy) on top of the fabric to prevent stitches from sinking.
Warning: MAGNET SAFETY. These are industrial-strength magnets.
1. Pinch Hazard: They snap together with enough force to pinch skin or bruise fingers. Always hold the handle/edge.
2. Electronic Safety: Keep them at least 6 inches away from computerized machine screens, credit cards, and pacemakers.
Prep Checklist (end-of-Prep)
- Stabilizer selected based on the Decision Tree above.
- Fabric marked with center crosshairs (using water-soluble pen).
- Fresh needle installed (appropriate for fabric weight).
- Scissor/metal tools moved away from the magnetic hooping zone.
- Spray adhesive applied to stabilizer (if floating/using magnetic hold).

Setup
This is the tactical execution. We are replacing "hoop wrestling" with "precision layering."
Step-by-step: first handling and dry-run hooping
- Base Layer: Place the metal hoop base on your flat surface by itself.
- Stabilizer: Lay your stabilizer over the base. Smooth it out.
- Fabric: Spray the stabilizer lightly, then lay the fabric on top. Align your crosshairs roughly to the center.
- The Clamp: Hold the top magnetic frame. Align one edge first (e.g., the top edge), then slowly lower the rest. Do not just drop it.
- Refine: If there are wrinkles, gently tug the fabric edge outward while lifting the magnet slightly in that area.
Sensory Check: The fabric should feel "taut but not stretched." Tap it. It should sound like a dull drum. If it's loose or rippling, you will get registration errors.
Checkpoints (before you ever stitch)
- Clearance: Check the underside of the hoop. Is the stabilizer flat?
- Orientation: Ensure the attachment bracket is on the correct side for your machine arm.
If you struggle to get the placement perfect every time, this is the trigger to investigate a hooping station for embroidery. A station holds the base item rigid, allowing you to use both hands to smooth the garment.
Setup Checklist (end-of-Setup)
- Hoop is closed; magnets are fully engaged (no gaps).
- Fabric is flat; no wrinkles in the sewing field.
- Inner grid template used for final centering check (and Removed!).
- Attachment bracket is secure and clean.

Operation
Now we attach to the machine. This is where "operator error" often occurs.
Step-by-step: your first controlled test (recommended workflow)
- Mounting: Slide the hoop onto the machine's pantograph arm. Listen for the click of the locking mechanism. Ensure it is rigid.
-
Trace/Trail: Run the "Trace" function on your machine.
- Visual Check: Does the presser foot hit the metal frame? CRITICAL: Magnetic frames are taller than plastic ones. If the foot hits the frame, you will break a needle or damage the machine.
-
Speed Dial: Start slow.
- Beginner Sweet Spot: 500 - 600 SPM (Stitches Per Minute).
- Expert Range: On a SEWTECH commercial machine, you might run 1000+, but on a home machine with a heavy magnetic hoop, keep it conservative to protect the motor.
Operational checkpoints (quality before speed)
- Sound Check: A rhythmic "thump-thump" is good. A harsh "clack-clack" means the needle might be deflecting off the heavy fabric or hoop. Stop immediately.
- Visual Monitor: Watch the fabric boundaries. If you see the fabric pulling inward (“flagging”), your hooping was too loose.
If you are comparing products, you might search for sewtalent magnetic hoops. Remember, the brand is less important than the compatibility and magnet strength. SEWTECH offers industrial-grade holding power that prevents the "fabric creep" common in cheaper alternatives.
Operation Checklist (end-of-Operation)
- "Trace" function run successfully (no frame collision).
- Speed reduced to <600 SPM for the first run.
- Machine path is clear (no walls/objects behind the frame).
- You are watching the first 1,000 stitches (don't walk away immediately).

Quality Checks
The stitch is done. Now, be your own harshest critic.
What “good hooping” looks like after removal
- No Burn: Lift the magnet. You should see zero shiny rings or crushed pile.
- Squareness: Rectangular designs should be perfectly rectangular. If they are skewed (parallelogram), the fabric shifted during the stitch process.
- Registration: The outline stitches lines up perfectly with the fill stitches.

Troubleshooting
Diagnose the problem before you blame the machine.
| Symptom | Likely Cause | Investigation (Sensory/Action) | Quick Fix |
|---|---|---|---|
| Shifted Outline (Registration error) | Fabric moved under the magnets. | Touch: Was the fabric taut? Check: Was the stabilizer too thin? | Use spray adhesive to bond fabric to stabilizer. Switch to Cutaway stabilizer. |
| Puckering surrounding the design | Fabric was stretched during hooping. | Visual: Are there wrinkles radiating from the design? | Hoop "neutral" (don't pull fabric tight). Let the stabilizer do the support work. |
| Needle Breakage or loud noise | Hoop collision or deflection. | Listen: Did it sound metallic? | STOP. Re-trace the design area. Ensure design is centered and fits the hoop. |
| Hoop "Pops" Open | Fabric too thick for magnet strength. | Feel: Did the magnet seal feel weak? | Use strong clips (if provided) or float the material on top of hooped stabilizer instead. |

Results
By integrating this walkthrough, you have moved from "unboxing" to "engineering a better stitch."
Your new baseline:
- Tools: 18×13 cm and 26×16 cm magnetic hoops verified.
- Safety: Magnets handled with care; machine arm measured.
- Skill: Ability to hoop felt and delicate fabrics without compression marks.
The Evolution of your Craft: Once you master magnetic hooping, your bottleneck will shift. You will notice that hooping is fast, but changing thread colors on a single-needle machine is slow.
- Phase 1: Eliminate frustration (Magnetic Hoops).
- Phase 2: Eliminate inconsistency (Hooping Station).
- Phase 3: Eliminate downtime (SEWTECH Multi-Needle Machines).
Embroidery is a journey of removing friction. You just removed the biggest source of friction—the screw hoop. Now, go create something flawless.
