I am curious to know if anyone uses sheets in their quilting and what for? I know some folks use them for backing but I have read/heard somewhere that if you have your quilt prof. quilted, sheets bind up the machine or make it skip stitches? Is this true? Also, does anyone ever cut it out for scraps? I use a lot of sheets for rugs and have lots of end pieces left that are in good shape. These are usually obtained from the thrift store and I only buy good strong sheets that are not worn out.
