Assemble Double Four-Patch Blocks
1. Join a solid blue 1-1/2x42" strip and an ecru tone-on-tone 1-1/2x42" strip to make a strip set. Press seam toward solid blue strip. Repeat with a solid blue 1-1/2x42" strip and an ecru star print 1-1/2x42" strip. Cut each strip set into 24—1-1/2"-wide segments (Diagram 1).
2. Join one segment from each strip set to make a Four-Patch unit (Diagram 2). Press seam in one direction. The unit should be 2-1/2" square including seam allowances. Repeat to make 24 Four-Patch units total.
3. Referring to Diagram 3 for placement, sew together two Four-Patch units, an ecru tone-on-tone 2-1/2" square, and an ecru star print 2-1/2" square in pairs. Press seams toward ecru squares. Join pairs to make a Double Four-Patch block. Press seams in one direction. The block should be 4-1/2" square including seam allowances. Repeat to make 12 Double Four-Patch blocks total.
