18" Add-A-Quarter Ruler

The Add-A-Quarter ruler from CM designs combines the speed of rotary cutting quilt pieces with the accuracy of using templates. Once your templates are made, the Add-A-Quarter will automatically add the customary 1/4" seam allowance to any straight angle and provide a straight edge for your rotary cutter. This product listing is for the 2.5" by 18" ruler. Other sizes are also available.
