Add-A-Quarter Ruler by CM Designs

This ruler and it's cousins (Add-An-Eighth & Add-Three-Eights) have been designed with a "lip" along one edge. It is perfect for foundation piecing to trim off the excess fabric with your rotary cutter before you sew a seam. I had done a lot of foundation piecing before these rulers came out, but the Add-A-Quarter made everything so much easier. It takes the guesswork out of trimming and sewing the seams!

This ruler comes in two lengths, 6" and 12" I use the 6" for most of my paper piecing, saving the 12" length for larger blocks. The Add-An-Eighth ruler is designed for miniature blocks and the Add-Three-Eighths ruler is designed for flannels. These rulers can also be used with a template, butting the lip up against the edge of the template and then cutting with your rotary cutter. These can be found at your local quilt shop.
