Assemble the Quilt Block
- Combine your 5-1/4" x 5-1/4" pink (or orange) squares with the WOW squares of the same size to make four quarter-square triangle units. Use my easy quick piecing instructions for assembly.
When you're finished, each completed quarter-square triangle unit should measure 4-1/2" x 4-1/2".
- Arrange the plain squares and the quarter-square triangle units into three rows, taking care to orient the triangle tips as shown above.
- Sew the components of each row together. Press seam allowances towards the plain squares unless you feel the color shows through too much.
- Sew the three rows together to complete the block, butting seams and matching patch edges. Press.
Your completed Ohio Star quilt block should measure 12-1/2" x 12-1/2". If your block is smaller than it should be, or skewed, press again and recheck. If it still isn't quite right, use my easy squaring-up method before swapping it or sewing it to other blocks.
