Half Square Triangle Ruler 1.5"

Are you tired of ruler rock? Me too! Bloc Loc rulers solve this issue by locking on the seam for solid placement and control over the ruler. This allows you to trim blocks 90% quicker than a flat ruler. It also helps seams end in each corner of the ruler. No more surfing the seam with your regular flat ruler. Trim half square triangles, quarter-square triangles, birds in the air, y-blocks, LeMoyne Star, double windmill, hidden square units among others.
