The Museum told me the dimensions of the pouch (10 cm circular base and 20 cm tall), so I made a pattern based on those dimensions. The pattern uses a round base of thicker leather, with the walls of the pouch as a single pieces that wraps around the circle and meets at the back of the pouch. I then extend the walls around the edge of the base piece and sew it to the bottom all the way around so that it gives a clean rounded edge. Then a sewed up the seam at the back.
This was my best guess as to how the pouches were done for the Fries Museum piece. I got the idea from a piece at the Museum of London.
I have to say, it looks bang-on to me. It sits the same way as the stick-purse example, and bulges at the base the same way. I think I've hit the nail on the head with the design.
Next step is to put the draw string on it, and add then to figure out the pouchlets. Then I have to start figuring out the handle.
