Nursery Bedding

I change my mind daily about what kind of look I want for the nursery. Of course, it somewhat depends on what i'm having which i find out on Nov. 4th but until then, I can dream right? So today I like the idea of using some colors that are popular right now- gray and yellow. Random for a nursery but that's kind of what I'm going for. I'm guessing that I will be buying fabric or large sheets and making my own bedding because I don't know if I will find anything that I like in baby sizes. So, the pic below shows kind of what i'm thinking. I can even have my friend Connie come over and paint the cool tree on the wall behind the crib. Here's the link to the web for a better view- Chiasso.
So, I need your help, if you see anything that fits with this theme, let me know. I was thinking the colors could be used for a boy also, just not so flowery.
