Oh yeah one of 'those' patterns. I know exactly what you mean because I just finished a block like that. If I would have read thru the whole pattern first, I know I would have constructed some the elements differently, which would have eliminated some of the bias.
There are better ways to construct the 8 HST's and 4 Flying Geese in each block. You will still need to deal with several bias edges but, hey, every one that can be eliminated is a bonus.
BTW your points on the block in your photo are exemplary!! Kudos!!
