Cellphone Cozy Necklaces Fashion pattern For those times when you just don’t want to carry a purse, but you need those necessities like a cellphone, credit card and a little mad money. The cozy hugs your phone to keep it secure, yet allows it to slide out easily when needed. Made using size 3 cotton crochet thread, or 2 strands of size 10 crochet thread, this pattern gives you the ease of crocheting with yarn but the beauty and durability of thread.
