Well it depends on what you are going to make. You would need a sander of some sort. If you are looking to make small wood crafts you would want a smaller detail sander (I have a ryobi and I love it). For larger crafts you would want a larger hand held sander. You can get a lot of these tools online at Sears.
Thanks for the advice. I definitely want to explore this hobby and try a lot of different things. I've done some similar stuff with wood a long time ago and I thought to start again.
