From the Tin Man bag…
Sew two House Block pairs together with the C2 roofs touching in the center. You should end up with a 12½” block with a center C2 diamond shape. Make 4.
Finish the Tin Man rows: Sew C3/C4 pieced blocks to the House Blocks in this order:
Pieced + House + Pieced + House + Pieced.
Press seams toward the pieced blocks. Make 2 – 12½ x 42½” rows.
