Not big on themes but I love airplanes and all things old. When I found out I was having a boy I immediately knew I didn't want to do blue (after having a father in the air force... I don't like blue but am fond of planes!)
The big red chair (it is a sleeper) and the red radio flyer wagon to use for toy storage.
Can't say that I have one. But I know what I like when I see it.
When I found something I liked I bought it. I then painted it later. The doors and drawers on the changing table had a purple stripe pattern. The red shelf was a goodwill find that was dark blue. Thank goodness for primer and paint in one!!
All the old toys and the changer.
Do what makes you happy. :-)
