We had picked this shower curtain out cause the husband loves blue and the different shades of blue seemed to fit with our vanity. We also painted the ceiling of the bathroom to an aqua color that was similar to the vanity top.
Then I had a blank wall with only a towel bar that needed to be filled with something. I went to Lowes/Home Depot and just picked up a lot of large paint swatches in the blue/aqua/gray families. I then cut them down to the same size and placed them in these floating frames. This is such a cheap thing to do and is so simple, that I hope someone else can use this idead if you haven't seen it somewhere.
