Pinwheel Block Pattern

Instructions

1. Cut two 6 7/8" squares

2. Sub cut each 6 6/8" square in half diagonally. You will be cutting on the bias, so be careful to avoid distortion. Yield=4 half square triangles.

3. From dark fabric: Cut two 6 7/8" square in half diagonally. You will be cutting on the bias, so be careful to avoid distortion. Yield=4 half square triangles.

4. Piecing Directions: Use 1/4" seam allowance throughout.

5. With right sides together, sew one light half square triangle to one dark half square triangle on the diagonal cut. Repeat four times to make four squares. Gently press seams together toward the dark triangles. Again, your are working with the bias, so avoid stretching the fabric.

6. With right sides together, join two pieced squares alternating light and dark triangles as shown in diagram. Gently press seams toward the dark triangles. Repeat for second pair of squares. You should now have two rectangles composed of alternating light and dark triangles.

7. Join the two rectangles as shown to form the block. Gently press seams toward the dark triangles.
