The CM Designs Ruler 6 Add-A-Quarter Plus is a versatile tool for quilting and applique projects. Made of recycled plastic, this ruler combines the speed of rotary cutting with the precision of using templates. It automatically adds a seam allowance to straight angles and offers a straight edge for your rotary cutter. Marked in 1/8 increments, it is perfect for foundation piecing, trimming excess fabric, and providing a straight line for the next fabric placement. The specially designed 1/4 lip and tapered edge make it easy to fold back foundation paper, making your quilting process fast and accurate.
