Web Design Deductions?

I'm trying to get my taxes ready, and the big thing I did in the last year that I haven't done before is, I made a couple grand doing web design (and a little writing income). I don't travel for it. I don't really have client meetings. The only expenses I can come up with so far are the domain names and my server hosting fees. I bought a laptop last year that I use for doing the design and writing. I think I can do some depreciation on that, probably? But is there anything else I can claim as an expense that I am not thinking of?

From now on, I am immediately depositing half of what I make from these situations into the savings for the end of the year.
