2cm x 10m roll of self adhesive washi tape with seam lines. Simply cut and stick to your sewing machine in your desired seam allowance position for a great guide to sew straight lines. No need to draw sewing lines, use the white lines on each side of the pink line for perfect 1/4"/6mm seams. Ideal for sewing half square triangles with a point reference.
