At the British Museum last Fall, I saw a 'pocket' that dates to the 1700s. Recently I had a close look at my photos and made one that looks pretty close to the original. Instead of silk, I used wool.
I wore this pocket while attending an event recently, the Kalamazoo Living History Show.
Perhaps you can see my pocket, hanging off my left side. Many thanks to James Townsend and to Chris Hornby for providing me with a place to sit. I was able to talk with lots of people introducing them to sprang, met a couple of former students, and enticed a couple of people to give sprang a try.
