Stars

Ohio Star

9-patch with quarter-square-triangle (QST) units in the cardinals. Each QST cell is split by both diagonals into four triangles meeting at the cell center; the two triangles aligned with the radial axis carry the star color, forming an hourglass that produces the Ohio Star's distinctive points.

How it goes together

  1. Step 1

    Cut your pieces

    Cut each region using the dimensions in the cut table for a 12 inch finished Ohio Star block. Standard 1/4 inch seam allowance is included.

  2. Step 2

    Sew sub-units

    Sew the smallest units first (half-square triangles, flying geese, four-patches), then build outward.

  3. Step 3

    Assemble the block

    Join the sub-units into rows or columns, then join the rows. Press as you go. Square the finished block to size.
