I have this product but have only tried one piece. I like to make things with selvedges. I put a piece of muslin down, then the FusiBoo, then the selvedges without sewing them. I just laid them down on top making them overlap slightly on the long edges. I used my applique pressing sheet to press the layers and VOILA! All the selvedges were lined up perfectly and all the layers are ready for quilting. I didn't have to sew each selvedge individually as I have been doing. This is a great product!
