Finally painted this for my bathroom. I've wanted some art in there since we redid it in the summer. I got the idea from a magazine... not sure what magazine though.
Basically just draw on the lines and then use a color on the bottom and add a bit more white to the paint for each layer above.
I'm probably just to lazy to do another coat but i kind of like how the paint isn't completely solid in each block and that its a bit streaky.
