Assemble Square-in-a-Square Blocks
1. Sew cream print triangles to opposite edges of black floral 4-3/4" square (Diagram 3). Press seams toward black floral square. Add cream print triangles to remaining edges to make a Square-in-a-Square unit; press as before. Repeat to make 18 Square-in-a-Square units total.
2. Sew together a Square-in-a-Square unit, four side units, and four red triangle-squares in three rows (Diagram 4). Press seams toward side units. Join rows to make a Square-in-a-Square block. Press seams in one direction. The block should be 9-1/2" square including seam allowances. Repeat to make 18 Square-in-a-Square blocks total.
