Diagonal Seam Tape is a perfect solution for sewing straight diagonal seams without having to mark any lines! Diagonal Seam Tape is made from a special washi tape that is strong, thin, and removes cleanly after sewing projects.
Simply place the Diagonal Seam Tape in front of the feed dogs with the red line in front of the needle as the stitch line. The black lines on either side of the center line represent a perfect 1/4″ seam allowance and are a great resource to use when making half square triangles, or learning to keep a perfect 1/4″.
You can use Diagonal Seam Tape anywhere in a pattern that calls for a diagonal seam, or anywhere it asks you to “draw a pencil line or diagonal line from corner to corner on the square”. Anywhere you would draw a pencil line, you can use diagonal seam tape to save so much time! Each roll is 10 yards.
