Unfortunately this project did not work at all. I tried several ways to apply the paint chips and ended up with bad results. After paint chips I tried gluing on Washi tape stripes, but the changes in weather and humidity made it all wrinkle up, fall off and just look like crap. I've since ripped most of it off. Let's just keep these photos here as a memory of what could have been. Maybe I should just paint the door.
It looked good when I first put the strips of paper up...
The next morning it just looked awful. So I tried it again with different adhesive...
And the morning after that, the new ones fell off. So I ripped it off for the second time and tried Washi tape instead.
I didn't feel like wasting time doing the whole door, just in case it fell through. So I left it like this to see how it would hold up. After our week long camping trip with the heat and a rain storm, the tape just peeled off, and bubbled up despite a coat of sealer. It looked terrible. I've since pulled it off and the door still needs to be taken care of.
