Yeah, everyone is right. I am too hard on myself. That's a recurring theme - trying to make anything I do be perfect. Anyway, personal shortcomings aside, I "fixed" the square. It didn't take 20 minutes. I just ripped out that square and a couple of inches each way and replaced the square with one that was almost straight.

I re-checked the other 10 little blocks and, including the saddle, 5 were off enough to notice. Tartan was right, they are printed wrong. Or, I distorted them when I pressed them. Also, I went back on added additional little seams to make sure none of white showed around the photo, so that may have added to the problem. I'm going to re-do them the best I can by blocking them as square as I can and re-sashing them. Then, I'm also taking a couple of days off from it. I get to volunteer today and tomorrow, teaching the kids to quilt.
Thanks again for your help.
