Add-A-Quarter with its specially designed lip, automatically adds the customary 1/4″ seam allowance to any angle and provides a straight edge for your rotary cutter. The tapered edge is used as a straight edge for folding back the foundation.
The Add-A-Quarter Ruler allows you to use your rotary cutter when foundation piecing to trim excess fabric and provide a straight line for placement of the next fabric piece. It combines the speed of rotary cutting quilt pieces with the accuracy of using templates. (Directions on package)
