This is the block with the highest number in any foundation pieced section.
Print or trace the block diagram onto foundation paper, number, and cut out as in the photo.
Important! You have to mirror this diagram.
Foundation piece the numbered sections and trim seam allowances to 1/4".
Using freezer paper to foundation piece, the paper did start running out of wax near the end of that 27 section center piece so I may split that in three next time.
Sew the three sections together.
