The red shelf was a lucky find. I hijacked it from my brother when he wasn't looking (no, seriously). It fits perfectly and can double as a bench (when not filled with toys). A group of carpet squares creates definition in the space and the most wonderful find- a big tree sticker.
The big blank wall was bugging me and I wanted something that would work for a play area but not look too juvenile in the living room. Check out Blik for some amazing wall stickers. I looked at a ton of wall stickers and this site had the coolest.
It was relatively easy to put up although I did ask a friend to come help. Thanks Dina!
