The CocoKnits Colorful Stitch Stoppers are perfect for double-pointed needles, circular needles, and straight needles. These foam stoppers are crafted from flexible EVA foam and accommodate US 0-15 needle sizes. Each package contains 4 of each of 6 sizes, totaling 24 pieces. We appreciate that these stitch stoppers slide down onto the needle instead of just resting on the needle tip, making them ideal for trying on garments and ensuring your stitches stay secure while you’re on the go.
