I think I'm going to try making some of these cute name blocks that I see you all making. I'm going to use flannel because I found some that matches the baby's room (for a friend's baby). Anyway, I was thinking of just cutting the pieces with pinking shears (is that what they're called? They cut a zigzag). Then I'd leave the zig zag edges out if that makes sense. My question is, will they fray? I don't sew a lot so I've not used flannel enough to know. I just thought it would be a nice sensory thing for the baby to have those zig zags. But I could just as easily add the ribbons if the flannel would fray too easily. Thanks for any input!
