Cut two squares, one light and one dark, 5-1/2" x 5-1/2" each. Using diagram below as a guide draw a diagonal line corner to corner on the back of the light square. Layer and pin the marked square on top of the dark square right sides together. Sew 1/4" from each side of the drawn line. Press flat. Cut on the drawn line. Press open toward the dark fabric. You now have two Half-Square Triangles. Square up these units to measure 4-1/2" x 4-1/2" square. For each block cut a center square 4-1/2" x 4-1/2".
These three blocks use eight (8) Half-Square Triangle units. Note color placement. Two of these blocks use three colors. Turn and sew the units together to create the block as shown.
