Diagonal Seam TapeTM (1⁄4" guide) is an innovative washi tape designed to simplify precise diagonal and straight-line sewing.
Instead of marking seam lines with pencil or chalk, simply stick this tape just ahead of the feed dogs-with the red center line aligned to your needle.
The two black lines on either side mark exactly a 1⁄4-inch seam allowance on each side, making accurate half-square triangles, strip piecing, and precision corners effortless.
The tape is strong, thin, and removes cleanly after each project-without residue.
Each 10-yard roll offers ample use across multiple projects.
