I'm trying to catch up...Is it me or are the blocks getting easier and easier?
Print or trace the block diagram onto foundation paper, number, and cut out as in the photo.
I mirrored the block because I wasn't sure whether it should be or not. I have the software, so mirroring blocks is no problem. If the block didn't need to be mirrored it doesn't make a difference anyway.
Foundation piece the four block sections following the numbers, and trim the seam allowances to 1/4".
