I'm currently working on a christmas quilt that will have white fusible applique on top of red patchwork. After searching the net over I've found a few articles that state I need to fuse muslin or any fabric behind the actual applique peice. Not one of these articles suggested a product for fusing or weather or not to window the fusing just like you do a normal applique piece. So any suggestions on fusing the two pieces together? I was wondering if there was a light weight fusible that would wash away? And if it would be large enough to do lets say a fat quarter, or bigger? Am I making any sense?
