Thanks... I must say it's a lot easier when I can see the other blocks around it. I knew what I could do before I took the tile in the first place. I've noticed too, that some people make it really hard to blend with their tiles by making them get darker just near the edge. The tiles I was working with here though were just perfect.

First of all, Great tile!

Yeah, I think that darkening of the borders is in most cases not intentional, its just the way that they cut and do the blending on their layers. Some people have the border of their tile as black, and somehow the black blends a little with the first pixel on each edge. I've noticed it quite a bit too.

(I'm the tile above you btw) :)
