Oh Anael, It is coming out so pretty. I love the Ohio Star blocks. I think your small world is going to be spectaucular with them. I really like the idea of scrappy light blues for the sky color in them.
I didn't catch your mistake until you pointed it out. I would turn it also.
I just finished a mini that had to have 2 blocks turned. Now, they really stuck out as wrong. But, I didn't really notice it till I took a picture of it. And, boom, there it was. I took the time to turn them also. But, I was really really glad that the mistake was in an outer edge.
