Before the holidays I had three quilts that were ready for quilting and binding. Each one was spray basted and to be finished before the holidays. Never happened! They were folded lenghtwise and placed on hangers out of the way. Today I am ready to start finishing them. There are a few wrinkles from the folds. Since these are spray basted, how would you go about removing the wrinkles? Can you iron with the spray basting there? What do I do?
