My use of a great technique making half square triangle unites from strip pieced squares. Strip piece two squares, turn one square so that it has strips horizontally, the other should be vertical. Put right sides together. Stitch all around the perimeter at 1/4" for seam allowance, then cut on the diagonals from corner to corner both ways. You will have 4 units. Press open and turn so the smallest section is in the middle and stitch as a four block. Voila!
