Creative Grids 15in Seam Guide Tool CGRSMN15

This 1/2 x15 inch seam marking 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. Our exclusive grip holds the tool in place while marking – the perfect tool when making half-square triangles!
