I made this set a while ago, and have been struggling to get enough decent photos to list it on Etsy. I still need some decent close-ups of the focal, which means I won't be posting it until I get a new tripod, but in the meantime, it can pretty up my blog.
The focal is a piece of brass filigree with a foil-backed green glass cab in the center. I bought it at the same place that I get all of my vintage keys at Gem Mall, and I'm pretty sure I got it for free. There was no price on the bag, and they're one of those vendors where they write all the prices on the bag, eyeball it, add it up in their head, and round it down to a nice even number. It's a little annoying for inventory purposes, but awesome for saving a few dollars.
