Stitch Stoppers - colorful. This is a CASE of 10 units. MSRP per unit is $12.00. Use these to keep live stitches on knitting needles when they're not in use. - Accommodate needle sizes US 0–15 (2–10 mm) - 4 each of 6 sizes - 24 pieces total - Made of EVA foam - Formamide and formaldehyde free We have never been a fan of knitting needle tip protectors – too often the force of the stitches have popped the guard off the end, or they simply fall off from the friction of being carried in a bag! We wanted a soft flexible something that would actually slide onto the needle and keep the stitches from sliding off. At first, we used earplugs with a hole poked in them – they would go onto the needle and do the trick, but they only come in ear sizes. So we had cylinders made of durable, EVA foam in a variety of sizes with an opening in the middle that accommodate everything from size 0 (or the cord of an interchangeable needle set) to a US 15. Problem solved!
