This little bundle is the perfect combination to help you set up for accurate seam allowances every time you sew.  Use the holes on the Seam Square to choose your seam allowance, from 1/8″ up to 3/4″ in 1/8″ increments, including both a scant and true 1/4″, then align your Seam Guide to the edge of the Seam Square, screw it in place and enjoy accurate seam allowances going forward.

The Seam Square will work with needles up to and including size 90/14.
