Using a Moda Jelly Roll right now. Its the first one I've ever used. I starched the heck out of them and havent had a problem. You might try that. I lay mine out on my ironing surface 9 at a time and spray till soaked and let air dry or almost dry then press, I seem to get less stretching and flaking that way. When I say press I mean I just set my iron on top of the fabric wait a few seconds and then pick up and move to the next section. I have notices while layering them for cutting that they were a little off but not enough to make a differnce.
