The Self-adhesive Seam Guide Tape from The Gypsy Quilter is perfect for domestic sewing machines. Simply cut to desired length and stick on to the bed of your sewing machine to create guidelines for sewing. Line up the center line on the tape with the needle on your machine to create guides for 1/4in seam allowances and more. No more drawing sewing lines for half-square triangles. To prevent residue build up on your machine, we recommend removing it in between projects.Made of: Paper & AdhesiveUse: Seam GuideSize: 3/4in x 10ydsIncluded: One Roll of Washi Tape
