Triangulations 4.0 contains all of the great foundations found in the earlier version PLUS Strip Triangulations. Strip Triangulations has been developed to address the needs unique to piecing with pre-cut strips When drafting the units, one of the angled points - a dog ear - has been eliminated, allowing the printed foundation units to properly fit the cut strips. Triangulations is PC and Mac compatible. STRIP Half Square Foundations sizes ½” to 4” in ¼” increments! Half square triangle foundations are now available in sizes up to 7 1/2" in 1/16" increments!
