Vicki,
Yes, I have used the dryer sheets and they work well. Once you have pressed the sides out after turning, cut away the extra dryer sheet leaving just a rim of dryer sheet. This will remove another layer if you are hand quilting.
Also, if you have a pile of sheets to press before using, cover your surface with a scrap of fabric as you will have a build up of "softener" on your pressing surface. Not pretty, but it smells great. Suzanne
