Make the Half Square Triangle Units
Half square triangle units, also called triangle squares, are used in each of the Shoo Fly variation's four corners.
- Use my easy sandwich method to create four triangle square units by pairing the two neutral background squares and the "floral" squares of the same size.
Assemble the Shoo Fly Variation Quilt Block
Refer to the illustration above to assemble the quilt block. Use /4" seam allowances throughout.
- Sew a triangle square unit to each side of a "floral" square as shown in the top left row of the illustration. Press seam allowances towards the center square.
- Repeat to make a second identical unit.
- Sew a "floral" square to each side of the block center as shown above in the second illustration from the top. Press seam allowances towards the outer squares.
- Arrange the rows as shown lower left in the illustration. Sew rows together, butting lofts where patches meet to form a perfect match at seam intersections.
- Press the quilt block and check its measurements:
- 12-inch finished block should measure 12-1/2" x 12-1/2"
- 9-inch finished block should measure 9-1/2" x 9-1/2"
- 6-inch finished block should measure 6-1/2" x 6-1/2"
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 sewing it to other blocks.
- 12-inch finished block should measure 12-1/2" x 12-1/2"
