I agree with the other posts so far.....It looks great if you step back and look at it as a whole.....truly, you are beating yourself up needlessly. I will share (admit to you) I had this same problem with a sew n' go project we did last week. It was a twister table topper that used the same block. I think I finally detected that I may have pressed some blocks tooo, tooo, much thus distorting some of the squares just a wee bit. These being cut on a bias, don't behave well once you start "ironing" them. I tend to press the heck out of stuff a habit I'm trying to break. So......onwards you go....it's going to be soooo very pretty when done, I just know it!
