FAQs
Does the size in the product title refer to the dimensions or the actual embroidery field?
The size listed, such as 3.9″ × 12.8″ (100 × 320 mm), refers to the inner hoop dimension, not the usable embroidery field. The actual sewing field is slightly smaller, about 3.1″ × 12″ (80 × 300 mm). For best embroidery results on COS models, always allow a margin of approximately 0.75 cm within the sewing area.
Is this magnetic frame perfectly compatible with my COS embroidery machine?
This Sewtalent magnetic embroidery frame is designed for COS embroidery machines, including COS-W1501G and COS-W1501L. Compatibility depends on choosing the correct brackets during purchase, as the set will be matched to your specific machine model. When selected properly, it ensures a secure and perfect fit for accurate embroidery operations.
Compared to my machine's original round hoop, what are the advantages of using this square magnetic frame for logos?
Unlike round hoops, the square magnetic embroidery frame provides a larger, more efficient area for rectangular or square logos. The flat sides help maintain proper fabric tension and alignment, which is especially useful when hooping sweatshirts or T-shirts. This design improves stitching stability and minimizes slippage for clean, precise embroidery results.
Are the top and bottom parts of the magnetic frame symmetrical, or do they have a specific orientation?
The top and bottom parts of the Sewtalent magnetic frame are precisely matched but not identical. Each section is uniquely shaped to ensure perfect alignment on COS embroidery machines. Both contain magnets that interlock tightly, giving consistent pressure and preventing fabric shifting during stitching, resulting in reliable, high-quality embroidery every time.
