This is a sandpaper board from Jen Kingwell Designs. This tool is a must for hand piecers! One side of the 8" x 101/2" board is sandpaper and the other side is smooth. Sandpaper boards are an essential tool for marking fabric for hand piecing and hand applique. The sandpaper grips your fabric and offers a great surface to mark with a pencil - without effort. The smooth side is a handy size lap board for arranging and pinning your applique shapes. This small size is perfect for hand work and travel.
