First, I bought a black roll of sticky-paste-on-thingy which costs only $5.90. If you want to buy ready-made decals, they can cost as much as $69.00. What for, right? I started drawing the lay-out. Decided to use all squares as most of the patterns in the toilet are edgy, so circles won't fit in. And they are passe, i guess. The Tools.
OK, slowly now. It's easy, but tiring. The alignment doesn't have to be perfect to give it that little poppish look. haha!
