Our diagonal seam tape is simply washi tape that is placed on the front plate of your sewing machine to act as a guide while you are sewing diagonal seams.
The red line in the center is aligned with the needle of your machine, and the black lines on either side are 1/4 inch to each side from the center of the lines, to represent a 1/4 inch seam allowance.
