This block is much simpler than it looks.
NB! If you're printing the block, remember to change the block size to 8"x5" before printing.
Print or trace the block diagram onto foundation paper, cut apart and number as below. Remember you can always click on a photo to see a bigger version if you have trouble reading the numbers or seeing the detail.
Foundation piece each section. Trim the seam allowances to ¼" exactly.
Assemble the block, making sure to line everything up correctly or your block will be "wonky". My top section is not quite straight, but I'm going to let it slide.
