This handy two in one from Creative Grids is a must have in your collection. Use the straight side of this double strip ruler to cut 1-1/2 and 2-1/2 inch strips – or use the pre-cuts that are on the market. Sew these strips together to create a 4-1/2 inch wide strip set. Turn-a-Round the ruler to cut five 60 degree triangles that finish 4 inches. Multiple layers can be cut at one time. The key holes in the ruler enable the rotary cutter to cut the sides without damaging the ruler. Used in the Aztec Diamond Cut Loose Pattern Sold Separately.
