Bloc Loc Triangle in a Square 6" Set

Bloc Loc’s Triangle in a Square Ruler Set contains two oversized cutting templates and a grooved ruler. Once the oversized unit is completed, the grooved ruler locks onto both seams so that it can be trimmed perfectly at 6 1/2″ x 6 1/2″.  This set creates perfectly pieced blocks that work with many patterns.
