I've made several "cases" for my husband and a friend of his. I did the same as Pattypurple did and I made mine out of an old velour blanket. I put ties on each side at the end and when folded over, they could just tie it. They're really simple to sew up and if you're using practice pieces with batting I don't see why those wouldn't work for transporting. DH keeps his in those cases all the time. Good luck!!!
