HI! I've made a few of those - one for myself and DIL, friends, etc. They are WONDERFUL. With Insul-Brite (JoAnn's has it) they will keep a bottle half full of ice - water to the top) for all day at least. I get so many stares and questions everytime I use mine. I made the strap long so that it can go "cross-body". I've always used my Batiks for it as well.
