During the time I had my daycare here, I painted lots of bright colors on the walls of the toy room. We had a family tree, a happy sun, a sleepy moon, cute caterpillars and butterflies, and a mail box. Would I leave out a rainbow? I think not, it takes up a whole wall in here.
I have since painted over some of the art, but several have become permanent fixtures on my walls, including the rainbow. I added a shelf to the wall and put my most precious possessions on the shelf....because we all know, these treasures, at the end of MY rainbow... are more precious than gold, and, a story yet to be told!
