Add-A-Quarter Inch Ruler``

The Add-A-Quarter ruler is perfect for use with a template to easily add 1/4" seam allowance and helps prevent template shaving when using a rotary cutter.

I use these specifically for Foundation Paper Piecing as the under-lip buts up perfectly against the folded paper and lets me cut a perfect seam allowance underneath my work! Definitely handy to cut measuring and stress in half for these projects!
