Assemble the Block
1. Sew together one tan print triangle and one green print triangle to make a triangle square (Diagram 1). Press the seam allowance toward the green triangle. Repeat to make a total of four triangle-squares.
2. Sew together the triangle squares in pairs. Press the seam allowances in opposite directions. Then join the pairs to make a block (Block Assembly Diagram). Press the seam allowance in one direction.
