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 the pieces in the cut list. The sizes are for a 12 inch finished Ohio Star block and already include a quarter inch seam allowance.

  2. Step 2

    Make the quarter-square triangle units

    Join the quarter-square triangles in pairs along their short edges, then join the pairs. Trim every unit to size before you join it.

  3. Step 3

    Assemble the block

    Join the units into rows, then join the rows. Press as you go and square the finished block to size.
