Half Square Triangles and batik fabric, what could be more fun? The Half Square Triangles are a cinch using the Square Me Up Ruler. Instructions include the 72” x 72” size as shown or a 56” x 56” size. This quilt could easily be adapted to be made even larger if that is what you need. The SMUP ruler will make this quilt a snap to sew. The half-square triangles go together very quickly. You can make it without the SMUP ruler using your favorite method of making half square triangles. What are you waiting for?
