Tashana explains it very well. I have only made place mats so far, but did something that looked rather like "A" Ironed it dry. Not a wrinkle or bubble! I have a full size top that I will try it on next. I expect it to work out just fine! Good luck! BTW Jan, I have wondered how the quilt turned out that you posted a photo of, that I believe was a round robin type? It had a strange round that you needed to work around. If you have posted photos sense, I missed it. Story of my life!!!
