Cut the pieces in the chart above. All measurements include a 1/4" seam allowance.
Lay all the pieces out as in the diagram. The block is a 9 × 9 grid, and each cell finishes at 2". Sew neighbouring pieces into sections, then the sections into rows, pressing seams in opposite directions from row to row.
Join the rows. The block should measure 18 1/2" now and 18" once it is sewn into the quilt.
