need help with calculations
My DD want a picnic quilt. She just wants star in the center with 1 outside border. I am making it 60" sq. I think that I want 24" center square 8 points for a typical star. I think I need to cut center 24", 12 7/8" sq out of 2 fabrics to make 1/2sq Triangles (4) and 12" with SQ for the corners. Add 6" border so finished size would be 60" does this math sound correct?
