Stitch clips are a great way to alleviate sagging sides if your are stitching with a scroll frame or Q-Snap. They also prevent your work from being pulled too tightly from side to side when working specialty stitches. These stitch clips attach to the fabric with plastic teeth that won't harm the fabric. Simply tighten the straps around the Q-Snap or scroll frame and secure in place with the Velcro ends. Each package includes four clips.
