I use the June Tailor Perfect Piecing sheets. They are non-woven sheets that come 25 to a package. You can run them through both the ink jet and laser printers with no problems. AND, you don't have to remove them. When you first finish your blocks, they will be stiff. I am hoping that washig will soften them up; but I haven't gotten that far in my project, which is a BOM from Stitchin' Heaven.
