Looking really good!
For a background, just go pickup a solid color blanket, or your fabric of choice from the fabric store. No need to spend more than $10-$20.
Thanks! The photos I took today are definitely the best I've taken to date. I'll definitely head to the fabric store this weekend and pick something up.
I think I'm going to look into making a makeshift light box for indoor pics. I bought a couple of hot lights years ago but wasn't ever able to figure out a way to get good diffuse light. I'm going to keep everything super cheap though and just work on technique and whatnot. I want to start taking photos of other stuff as well and am thinking I'll take my camera to my next league night.
