Stash that cash in a cute crochet coin purse with a quirky chain detail. These little purses have 3 1/2" pinch purse frames. The pinch purse frame is installed in a "casing" around the top opening of your purse. When you pinch or squeeze in the ends, the frame opens the purse. When you release the pinch, the frame snaps shut.
If you prefer not to use a pinch purse frame, you can use hook and loop tape (Velcro(tm)). Be sure to get the softest one you can because you'll be sewing it on by hand.
Exact gauge is not necessary. This pattern however, is calculated using a gauge of 8 sc and 8 1/2 rows = 2" (5cm) using Bernat Handicrafter(r) Cotton yarn.
Knit, Sew, Bake, Repeat. That's me!
