Assemble Quilt Center
1. Sew together two A blocks and one B block to make a pieced row (Diagram 7). Press seams toward A blocks. The pieced row should be 6-1/2x18-1/2" including seam allowances. Sew a light gray print 6-1/2x18-1/2" rectangle to each long edge of pieced row to make a side unit; press seams toward rectangles. The side unit should be 18-1/2" square including seam allowances. Repeat to make two side units total.
2. Lay out one A block, four B blocks, and four C blocks in three rows (Diagram 8; note rotation of C blocks). Sew together blocks in each row. Press seams toward A and C blocks. Join rows to make a center unit; press seams in one direction. The center unit should be 18-1/2" square including seam allowances.
3. Referring to Quilt Assembly Diagram, sew side units to opposite edges of center unit to make table runner center. Press seams toward side units. The quilt center should be 18-1/2x54-1/2" including seam allowances.
