How to make a 15" Cat's Cradle block

  1. Cut the pieces in the chart above. All measurements include a 1/4" seam allowance.
  2. Cut the squares marked "cut once" in half on the diagonal. Each gives two triangles. Sew them to their neighbours along the long edge first and press toward the darker fabric.
  3. Lay all the pieces out as in the diagram. The block is a 6 × 6 grid, and each cell finishes at 2 1/2". Sew neighbouring pieces into sections, then the sections into rows, pressing seams in opposite directions from row to row.
  4. Join the rows. The block should measure 15 1/2" now and 15" once it is sewn into the quilt.
