Where can I find an inexpensive sex neutral baby bedding set?

I'm having a baby in less than 10 weeks and our nursery is not anywhere close to be done. We have been told that we are going to have a girl but I wanted to have a gender neutral room just in case there was a mistake and also because we might have a boy baby and they have to share the room for a little while. Anyways I've been looking everywhere u can think of for a bedding set. I have gone to every single store and yes I have checked eBay and other websites like it. I have looked for fabric to get it costume made too but I can't find anything I like. Everything is too pink or too blue or has monkeys on it. Please help me. I'm frustrated. The walls in the room are light yellow-green and the crib and the change table are espresso. The flooring in brown. Please send me links of specific sets and not the stores that sell them cause I've looked pretty much everywhere and thanks!
