I'm thinking it might be a good idea to use a thin interfacing on the backing sheet before layering. I would have to look to be sure, but I think Pellon 99F is a good lightweight interfacing and not too expensive. Walmart probably carries it. Or use Misty Fuse to fuse a new sheet to the back of the Alf sheet. Both options require a little more money and an investment of time and effort, so it would depend on whether you would want to do it for her.
