1. Use a pencil to mark a diagonal line on wrong side of each pink print and red swirl print 4-7⁄8" square.
2. Layer a marked pink print square atop a green tile print square. Sew together with two seams, stitching 1⁄4" on each side of drawn line (Diagram 1). Cut apart on drawn line to make two triangle units. Press each triangle unit open, pressing seams toward pink print, to make two green triangle-squares. Each should be 4-1⁄2" square including seam allowances. Repeat to make eight green triangle-squares total. Repeat with remaining marked pink print squares and burgundy print squares to make eight burgundy triangle-squares.
3. Using marked red swirl print squares and small green print squares, repeat Step 2 to make 16 red triangle-squares.
