Any tips for making a DIY headboard?

I want a headboard for my bed. I want to make one myself since I am currently, as the french would say, le broke. Keep the following parameters in mind:
1. I have a full size bed
2. I have very little money to spend
3. I have very little DIY skill. I can handle basic sanding/painting/nailing, etc. But no power tools should be involved (I am a klutz).
4. Cannot take forever to make, because I get bored easily and will surely abandon a project midway if I get bored.
4. The colors in my bedroom are currently red, black, and white.

Any ideas/tips would be appreciated, for the assembling part as well as the designing part. I am not the least bit creative! Even specific websites to check out for ideas would be swell. Thank you, fellow flutherites!
