I dread working with backing. It's big, it's hard to wrangle on a ironing table much less a regular ironing board. It gets all wrinkled up about as fast as I can iron it. I had this big 108" wide backing fabric and it was full of folds and wrinkles. I pinned it to my design wall and had it ironed in about 5 min. I will spray baste the batting and quilt top on it and then fold and move it up to get the lower section ironed. The ironing is keeping the fabric snug on the wall, it is clinging very tight.
