I snuck a block in before it got too dark to take photos.
Print or trace the block diagram onto foundation paper, number, and cut out as in the photo.
Following the numbers, foundation piece each section of the block. Trim the seam allowances to 1/4".
Referring to the block diagram, sew the pieced sections together.
If you start with the outside sections and work inwards, you will see where the seams should be aligned.
