I think the most taxing part was trying to trace half of it and then have that half mirror itself perfectly. Hmm, yes, that was the worst part. haha

And I'm very glad you like them! :)

Edit: Oh, and because I cannot remember if I already commented on your scans posts or not, I just wanna say a big, huge THANK YOU for sharing scans from 8UPPERS and other recent albums/singles. (As you've probably already noticed by now from the credits on the wallpapers, the scan from which I traced that card was yours~ :Db)
