**Creative Grids 15in Seam Guide Tool

This 1/2” x 15” seam marking tool is long enough to mark the diagonal of a 10” square. Mark through the slotted center with any mechanical pencil and sew 1/4” on each side of the line. Or mark the sewing line by drawing on both outside edges of the tool. It's the perfect tool when making half-square triangle blocks.

The tool slides easily over the fabric until pressure is applied. Then, the exclusive grip holds the fabric in place while marking.
