When our group did the Winter Wonderland embroidered project, a couple ladies used the fusible, I chose to baste muslin to the backs of mine. A word of caution, if you choose to iron fusible, you need to do it BEFORE you trace with a wash away marker or you will set the ink. ALSO one of the ladies used an iron that was too hot, her project had the bubbles that come up from the glue if it's too hot. I do hand embroidery with or without a backing, depending on how I feel at the moment. My latest project, I've basted some warm'n natural to the blocks.
