Chels --- something like this would be cute in baby R's room, throw in purple, and replace the real pictures for the cute etsy prints! Family Picture Gallery Wall by Tatertots & Jello featuring Cut it Out Decorative Wood Cutouts. Love the color!
Place painted foam board in the back of the bookcase, giving the look of a painted bookshelf w/out the commitment. Love this idea for a small book shelf next to couch. Good way to use yellow without committing to it in a big space.
