I would LOVE to share pictures of my playroom! DH was out of town for a week over the summer, and I decided to 'surprise' him (aka just do it and not have to worry about him thinking that it wasn't the best idea, I have a history of biting off more then I can chew ) by redoing the playroom, which was a room we had not touched since he bought the house in 1997. I worked my butt off peeling wallpaper off, spackled and scrubbed the walls, and finally painted. It was a ton of work, but I love the way it turned out. The only thing left to do is replace the carpet, which we will do once DS is totally potty-trained. The room itself is tiny, maybe 9' by 12', but is bright and cheerful.
Also, I made the bookshelf myself this summer with plans from Knock-Off Wood. It keeps all the kids books fairly manageable, but doesn't take up too much space.
DSS biggest by far
DD littler
DS littlest
