I've got my sets complete. And even though I thought I was being careful, I had to rip out four sets as I got the white on white neutral sewing on face down.
But my biggest mistake (and I hope it does not mess me up) is that I got mixed up cutting my 2" squares, and have 80 cut of the constant. I know I started out with more yardage than suggested, so hopefully we'll either need more 2" squares at some point, or I'll have enough yardage left that I won't end up wishing I had another 4" on the end!
