Question regarding aida fabric for block
I have completed embellished cross stitch patterns that I would like to make into quilts. They are on aida fabric. Someone told me to use muslin on the back. Does this mean to stitch around the edges to put the muslin on the back or should I use a fusible something on the back? I do not know what to do or what to use. Can someone help me, please, so I do not ruin my pieces? Thank you.
