Creative Grids Half Sixty Triangle Ruler bgut_odd write on it with greaseUse the Half Sixty Triangle Ruler from Creative Grids to cut setting triangles for the Creative Grids 60 Degree Triangle Rulers. Sew two triangles together to create a 60 degree triangle or half rectangle. You can also cut a wide variety of shapes that will fit into a 60 degree grid. The ruler slides over fabric until pressure is applied. Then, its grip feature holds the fabric in place while cutting, eliminating slipping and miscuts.
