My daughter loves to take all of the dish towels out of the drawer and play with them. And I hate it! All of my towels are thrown all over the place and in the laundry almost all the time. It is very frustrating!
So I'm sure you have heard of this, but just in case....
Get some Velcro and sew it on.
Turn the towel over a few inches enough to go over the handle of the oven. Sew on the other piece of Velcro.
Again the best invention ever.
