I painted a rainbow in my tile. It is very cool to know now that it was not 'just' a rainbow, but a part of my personality. Still to this day i love bright decorative colours and patterns in clothing, decor and art.
A few years ago i found my tile on the wall and i was looking through the column above my tile and i was very surprised to see in the column right next to mine was the tile of my high school boyfriend. We met 6 years after the tile wall was made. We never knew about this at the time. We lost touch over the years. But it is very neat the wall has this other 'secret' hidden for us to remember!
