How to make a 15" Ohio Star block
- Cut the pieces in the chart above. All measurements include a 1/4" seam allowance.
- Cut the squares marked "cut twice" on both diagonals. Each gives four triangles with the long edge on the straight grain: these are the large triangles in flying geese and hourglass units.
- Lay all the pieces out as in the diagram. The block is a 3 × 3 grid, and each cell finishes at 5". 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 15 1/2" now and 15" once it is sewn into the quilt.
