Diagonal Seam Tape from Cluck Cluck Sew is a printed washi tape that sticks to the bed of your sewing machine and acts as a permanent stitching guide, supplied on a 10 yard roll. A red line runs down the center to follow when sewing corner to corner, with black lines marking a quarter-inch seam allowance on either side. The point of it is that you stop drawing on fabric: instead of marking a diagonal line on every square before you sew, you line the corners up with the tape and stitch straight down it.
That saves real time on the units where diagonal seams pile up — snowball corners, flying geese, half-square triangles, binding joins and stitch-and-flip blocks of every kind. The tape is thin enough not to catch fabric as it feeds and strong enough to stay put through a long session, and it lifts off cleanly when you're finished, leaving no residue on the machine. At 10 yards a roll, it lasts well past a single project. This listing is for one roll of tape; no other notions or machine accessories are included.
