Using these Jimmy Beans Wool lamb tape measures is a breeze. When you need to measure your knitting or crochet pieces, just gently pull on the lamb's tail. It will stretch out to become a handy tape measure. As for the care, keep them away from sharp objects that could tear their tails. If they get dirty, you can use a soft, dry cloth to gently wipe them. Store them in your project bag when not in use to keep them safe and ready for your next crafting session. Enjoy having these cute companions by your side during your creative work!
