So here's the problem with water-based decals: They move so long as there's water on them. That seems pretty obvious, but that almost means after you're done with one and you're adding a second one right next to it, like literally they're overlapping, the water from the second decal will go onto the other and then you have two moving around all over the place like assholes. I have no idea why anyone thought these would be a great idea.
