Handy Tape II
A measuring tape you can stick to your machine bed. Adhesive will not harm your machine finish and is repositionable and reusable.
Makes a perfect seam guide for accurate 1/4" and 1/2" seams, and sewing corner to corner on squares to make half square triangles.
If you have ever taken any of my classes or workshops you have probably seen me use this to mark machines for accurate strip sewing.
Comes in a handy dispenser.
