Assemble Pieced Triangles
1. For one pieced triangle, gather a set of matching B, C, and D trapezoids from one tone-on-tone and a floral A triangle.
2. Sew B trapezoid to A triangle to make an AB unit (Diagram 1). Press seams open.
3. Working in clockwise order, add C trapezoid to the AB unit to make an ABC unit (Diagram 2). Press seam open. In the same manner, sew a D trapezoid to ABC unit to make a pieced triangle (Diagram 3). Press as before.
4. Repeat steps 1-3 to make 28 pieced triangles total. You will have two sets of trapezoids left over.
