Yes, I have washed blocks made using the C&T product and Quilter's Select Print and Piece Fuse Lite. Most of the fibers come out, not 100%, the package says that, but the applique's are soft. Best advice I wish I had known 8 years ago when I started Ruffled Roses with the C&T Wash Away Applique' sheets is to soak each block when finished, not wait until the entire quilt is finished, quilted and bound. The longarm quilter had no problem quilting the applique's but the quilt is heavy and must be washed before I enter it in a show. I am using Quilter's Select Print and Piece Fuse Lite on a current project and EACH block is soaked in warm water in the sink when it is stitched. Nice and soft though I am sure some of the fibers remain. It serves as both a stabilizer for the machine appliqué' and, since I printed it directly on the sheet, it is the pattern as well. Very easy to use.
