That's a great idea. The ideas that moms come up with are great and very useful.
. Just a piece of advice for those zippers that separate. I got this info from a lady who runs a sewing store. If you gently squeeze the main part of the zipper with a pair of pliers on both sides. Key word is gently. That should help those seperating zippers, it's because all the pulling of the zippers up and down that causes them to open up a bit more so the teeth don't get squished together right or totally.
