In the grand scheme of useful accessories, this is my most useful. You can buy some beautiful pocket belts around the interwebs, or you can make your own from an old pair of cargo pants (I know…more cargo pants, but they really are very good starters for steampunking).
2. Bolt Snaps
Perhaps not so notable in and of themselves, but the best solution I have found for clipping all my favorite accessories to my belt or corset are these bronze double ended bolt snaps. You can get these handy little guys in various sizes, styles, and finishes online, from a local hardware store, or from a marine supply shop. I happen to find this particular design the most useful.
3. Magnification Lens
I can’t remember where I picked up this little field lens, but I think it’s adorable. It’s just a bit of a magnifier, and it telescopes closed. I have used it to take a closer look at items in a dealer’s room, but it’s mostly just for show. I really love it because it reminds me of my former life as an archaeologist.
