The  Creative Grids® 15-inch Seam Guide Tool is long enough to mark the diagonal of a 10-inch square. Mark through the slotted center with any mechanical pencil and sew 1/4 inch on each side of the tool. Or mark the sewing line by drawing on both outside edges. Exclusive grips hold the tool in place while marking – the perfect tool when making half-square triangles!

Total Size – 1/2in x 15in
