In my attempts to repeat this pattern, it revealed it's flaws to me. I don't recall where I saw it, but I remember a tutorial about tiling patterns. (assuming I remember it correctly) You divide the pattern into quarters and switch the top right with the lower left, and top left with lower right. This then allows the outer edges to align properly when printing. Kind of like turning something inside-out.
I can't get it to line up! So, now I either start over or try to find what's causing the flaw.

CORRECTION: I found the tutorial. And it's by, none other than, Julia Rothman on Design Sponge. I bookmarked it (Thank you Delicious!) and there it was, waiting for me to rediscover it!
