1. Referring to Diagram 4, sew together four Square-in-a-Square units, four light print 4-1/2" squares, and one light olive green print 4-1/2" square in three rows. Press seams toward light print and light olive green print 4-1/2" squares. Join rows to make block center. Press seams toward top and bottom rows. The block center should be 12-1/2" square including seam allowances.
2. Referring to Diagram 5, sew rectangle pairs to top and bottom edges of block center. Press seams toward block center. Sew a navy blue print 2-1/2" square to each end of two rectangle pairs to make two pieced units. Press seams toward navy blue print squares. Add pieced units to opposite edges of block center to make a block (Diagram 5). The block should be 16-1/2" square including seam allowances.
3. Repeat steps 1 and 2 to make five blocks total.
