Large Fabric Clips, 14 pc

I've been using these for quilting and they grip several layers of cotton without slipping, which pins never managed. The tension is strong but they don't leave dents in vinyl like my old clips did.

Basted a leather tote this weekend and these clipped through the 5/8" seams without leaving a single hole, which pins always did. The spring tension is strong but not so tight that my fingers ache after an hour of bag-making.

These held together four layers of vinyl without leaving a single pin hole, which is exactly what I needed for the tote bag I was making. The 5/8" capacity handled the thick seams fine, and the grip never slipped while I was sewing.
