The strap is knitted mohair, very nice to hold and stretchy enough to sling on your shoulder if you like to do it that way. Or you could pretend you're the Queen of England and sling it on your arm for your official royal portraits. I'm using these knitted ties as purse straps and they work very well. I knew there was a reason I got on a tie knitting tear a while back there.
And there are pearls, and tiny blue glass beads and Indian metallic thread couched on. Great fun to do. I must find my thimble if I'm doing any more denim hand sewing, though. My fingers are pretty peppered with needle backups.
Anyway, here's a front view and a back view, or you might say a frontispiece and a backispiece.
