I like your block -
A lot of people - me included - make the HST (half-square-triangle) units - the red and white units in your block - slightly oversized and then trim them down.
Example: if the directions say to cut a square 2-7/8, we cut the square 3 inches - and then do the diagonal sewing - and then cut the squares diagonally - and then trim them -
When I cut the square sizes "exactly' - even when I sewed "a very scant 1/4 inch seam" - my units ended up skimpy (too small) - so I add plus 1/8 inch to the directions for those units.
Only one of your eight HST units has noticeable points issues - Now the question is - what happened with that one?
How did you make yout HST units? There are several ways to make them.
I still need to measure each section to see if it's the size I want it to be - it's easier to "adjust" as I go, then when the block is "finished"
Would you be willing to also show a picture of the back of your block? That's where we might be able to get more ideas of where that one unit is wonky compared to the others.
