I double and triple checked and the center square is cut 2 5/8" and I followed the directions and worked my way around but it just doesn't fit in the middle, it bunches up, and doesn't line up after that last turn, so I'm guessing it is because I am not using a "scant" measure. I never have, I think it's weird it was ever started by whomever. I mean, define "scant"

. The first three BOTM came out the right size and I used my 1/4" foot.
I can move my needle to the right, so scant means skinnier than a normal 1/4' seam? How will I ever know if I have it scant
enough unless I sew the block over until it turns out? This is a complicated pattern to practice with.
Could I just make my squares 1/4" bigger before I cut them into HSTs?
There's always a bright side ... I'm going to pick a different color combination this time because the colors I chose blended together too much.
