@ibex94 I confess that I deliberately chose the “easier” of the options for each month, and they all came together with no problem, though with my (lack of) precision skills, I still had a couple of blocks that ended up a bit too big (don’t look too closely at the points lost in the sashings…) or a bit too small (saved with more scant seam allowances with the top construction for the most part.)
On one of the blocks, I reversed the colors of the “body” and the “wings” of the flying geese units and ended up with an “alternate look” for that block, but that’s on me! LOL
