In my patterns, I often mention the word ‘clip’. With that I point to (wonder)clips. The word wonder is between brackets since that is a registered brand. You get 4 regular, 2 large and 4 mini clips in this order.
Clips are for bagmakers what pins are for a tailor. Indispensable. The bottom of a clip is flat so you’ll have no problems to keep them on your fabric while you stitch.
