1. Use a pencil to draw a diagonal line on wrong side of each mottled tan 4-7⁄8" square.
2. Layer a marked mottled tan square atop a batik or bright print 4-7⁄8" square. Sew pair 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 triangle units open, pressing seams toward mottled tan, to make two triangle-squares. Each should be 4-1⁄2" square including seam allowances.
3. Repeat Step 2 to make 80 triangle-squares total.
