The August Stash Builder Block of the Month is the princess Charlotte block. To construct this block we will use bisected triangles to make half square triangle units and flying geese to eliminate a lot of the waste that usually happens when making flying geese.
Fabric A: Cut 1- 3 ½” square
Fabric A: Cut 2- 3 ⅞” squares
Fabric B: Cut 4- 3 ½” x 2” squares
Fabric B: Cut 2- 3 ⅞” squares
Fabric B: Cut 1- 4 ¼” square
Fabric C: Cut 4- 2 ⅜” squares
All seam allowances are ¼”. The block will be 9” square to match the other Stash Builder Box Blocks of the Month.
1. Cut the Fabric A and Fabric B 3 ⅞” squares in half on the diagonal.
2. With right sides together, put one Fabric A triangle on top of one Fabric B triangle. Stitch together on the long side to form a half square triangle unit. Repeat with the remaining triangles.
3. Open and press to the dark side.
4. Trim to 3 ½” square.
5. Cut the Fabric B 4 ¼” square into fourths on the diagonal. Cut the Fabric C squares in half on the diagonal.
6. With right sides together, sew a Fabric C triangle on each of the short sides of the Fabric B triangles to form a flying geese unit. Repeat with the remaining triangles to make four total.
7. Open and press to the dark side.
8. With right sides together, attach a flying geese unit to the long side of a rectangle, according to the photo below.
9. Repeat with the remaining flying geese units.
10. Press and trim to 3 ½” square.
11. Lay out the block according to the photo below.
12. Sew the units together in each row.
13. Press the seams on the top and bottom rows to the outside. Press the seams on the middle row to the center.
14. Sew the rows together.
15. Do a final press and trim to 9” square.
