Well, I haven't done any more sprang, yet.
I toyed with the idea of taking Sarah Goslee's (a.k.a. Phiala) tablet weaving and sprang class at the Peters Valley craft centre, a class which starts in a couple of days.
Then I plunged into a little online research. If you judge by the Weaver's Hand website, there are three known sprang instructors: Sarah Goslee, Carol James, and Blue van der Zwan-Deen (Den Blauwen Swaen).
I saw a reproduction of Admiral Lord Nelson's purse on Carol James' August 17, 2011 blog post, "Sprang is Here" then a similar item labled as a reproduction tobacco pouch on van der Zwan-Deen's website on the page about her teacher Ms. Bos. I'd recently read a decade-out-of-print map book of Virginia, looking for things to do, and noticed a tobacco and textile museum. The very place you'd find a sprang tobacco pouch, I thought. The museum no longer operates, sadly. So I turned to Colonial Williamsburg's website and found stocking purses in their online Historic Threads exhibit.
A stocking purse is the same type of bag as Nelson's purse and the tobacco bag. It works with a nifty closure of a sliding ring that will make sense when you see it, low tech and yet brilliant. The bag's structure is distinctive compared to other purses in the series, exactly like a limp stocking without shaping. The earliest is worked in sprang, and then there are others worked in knitting, crochet, and netting of some kind. The knitting is knitted lace that resembles the pattern of holes in the sprang version. I must try working sprang with holes soon.
I suppose the stocking purse is the reason for the expression "sock away your money."
