I am a sucker for stripes and chevron, and I love gray. We knew we had a white crib, so I thought the gray would like really good with all white furniture. So, we decided to paint all the walls gray except for one wall, which we would stripe with gray and white. The stripes were extremely easy to do and I almost wish we would have striped one more wall, but I'll deal.
The ABC's are gender neutral and I can use that same theme with different accent colors the second time around. My mom's good friend made these beautiful canvases for us to hang on the wall. I am obsessed with them. The gray matches the paint on the wall, so they will blend in, but the best past is if and when we sell our house we can take the canvases with us rather then the ABC's being painted directly on the wall.
