Diagonal Seam Tape

Diagonal Seam Tape is placed on the sewing machine to make sewing diagonal seams easy with no marking lines on the fabric first! It is placed in front of the feed dogs of the sewing machine, with the red stitching line in line with the needle. The black lines represent a perfect 1/4" seam allowance, which helps guide fabric, make HST's without marking lines, and is a great help for beginners learning to sew and keeping long strips of fabric straight. Each roll is 10 yards.
