CONSULTATION & RECOMMENDATION
L. Sewing invisible zippers
- When sewing invisible zippers, a specialized feed dog should be used to ensure the stitching line
stays outside the zipper tape fold. This helps keep the zipper teeth upright and allows the tape to
remain flexible.
- Depending on the fabric thickness and design requirements, it is important to choose an appropriate
zipper size to ensure durability.
- Currently, HKK offers invisible zippers in the following sizes: #3, #4, and #5.
