FAQs
Can I use this 12.6″ × 3.9″ (320 × 100 mm) hoop to embroider small accessories like ties or socks?
Yes. This hoop size is perfect for 'floating' small items. Simply hoop a piece of sticky stabilizer or base fabric, and place your item, such as a tie or sock, on top. On COS-W1501G or COS-W1501L machines, this setup allows smooth magnetic embroidery hoop use without stretching or misalignment on small and irregular materials.
Are the top and bottom magnetic frames symmetrical, or is there a specific orientation?
The Sewtalent magnetic embroidery frame has a unique top and bottom design. Each piece is shaped to align precisely with its counterpart to ensure consistent magnetic strength. Both sides contain embedded magnets that keep the layers perfectly matched, maintaining stability and fabric grip throughout the entire stitching process on COS embroidery machines.
Will my COS embroidery machine automatically detect this hoop size?
Typically, you will need to manually set the hoop dimensions in your COS embroidery machine’s software. The actual sewing field is about 11.8″ × 3.1″ (300 × 80 mm), so make sure your design fits within this area. This adjustment ensures full compatibility, optimal placement, and accurate hoop recognition for your magnetic embroidery frames.
Do I need to apply protective stickers to prevent fabric scratches during embroidery?
Not necessarily. Sewtalent magnetic hoops feature a polished surface that’s safe for most fabric types, reducing friction and preventing marks. However, users working with highly delicate or slippery materials may add a light tape layer, such as painter’s tape, for additional grip and to maintain smooth embroidery performance on COS models.
