We had almost finished this project, and then we let it sit for a long long time. We just never found the time to fix up the lines. Every time one of us would use that bathroom we would have a moment of "oh yeah, this needs to be finished". And then promptly forget about it again after leaving the bathroom. Well, no longer! It is finished!
We had originally thought to add some yellow/orange lines to match the drawing of the scooter on the opposite wall, but then I had the brilliant idea to just buy a hand towel in that colour to give it an extra pop of orange. It was hard to find one that matched exactly, this one is a bit more yellow, but it still has the same effect.
A big thanks to my mother, who helped make the finishing of this project happen! She painstakingly fix up the lines that had bled under the tape with a fine paint brush.
Everyone who uses the bathroom seem to be excited by the pattern on the wall. It is unexpected, and unseen until you are inside the room, which adds to the dramatic effect. I'm quite happy with it, and it is so original compared to using generic wallpaper.
