We converted our guest bedroom into a nursery. It was already painted yellow so there was not much work to be done.
I didn't want the room to look like I went to the baby store and bought all matching items.
Shop around. Nursery decor doesn't have to come from a baby store.
I love the mobile I created. When the heat or air is on the butterflies move slightly. I loved the paper mobiles I had seen in some stores but didn't want to spend $75 on one. Mine cost about $12.
