Another fan of Mabel Labels. My younger kids are 13 (boy) and 12 (girl). I don't use them on the boys stuff anymore except jackets which is only a one in Florida and a few hoodies. I use Mabel Labels on ALL of my daughter's cheer clothes, jackets, sweaters, nike pros, etc. She does a lot of sleep overs and loses items. The cheer clothing she has 24 other girls on her team with identical items and I like ours to be returned and her not get a random warm-up jacket, shoes etc. that may not be in the same condition. I have never had an issue with Mabel Label's washing off.
