#BOTMSBB: Princess Charlotte

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.

Cutting Instructions

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.

Assembly Instructions

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.

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.
