I made my first steampunk costume for our local renfaire over the summer, I guess because my nerd street-cred was slipping. It turns out I really enjoyed putting the whole thing together, particularly making the pistol I wore. It also got a pretty warm reception here on DeviantArt, with a few people asking if it was for sale.
So I've decided to put a bunch of weapons together, with an eye on setting up an Etsy store when I build up a bit of an inventory. So far I've been having a great time, and it's been fun making three-dimensional art for a change.
