The Cutting EDGE Quilting Rulers feature a patented design with a diamond carbide edge that sharpens rotary blades with every cut. These revolutionary rulers come in 17 popular styles and offer easy-to-read numbers, square-up guides, and diagonal dots that make lining up cuts quick and accurate. Clear backing with non-skid dots allow you to see over your working area with no obstructions while keeping the ruler in place. The red lines are designed to "tuck" your bock into. Use the inside EDGE of the red angle to cut squares and trim up blocks. The diagonal has extra large dots for fabric positioning.
