I don't understand WHY you're not supposed to put them in the dryer?? My fabrics are all cotton with cotton batting & the fabrics have been pre-shrunk. I once made a set of placemats & the pattern said to PUT them in the dryer & they're fine! We live in a townhouse & are not supposed to have clotheslines outside. ( I have dried my sheets outside, though) Certainly no room to dry them flat!! I need a bigger sewing room as it is! lol.
