Miser bags are seen throughout the late 1800's through the early 1900's. This one is based off an original pattern from 1922. I'm not exactly sure how they get their name. Maybe because you divide your money between the two pouches and spend half and hoard the rest.
Most of the bag is crocheted with single crochet, and the designs are done with Czechoslovakian glass beads. I don't know exactly how long it took to make, but I did have to rip out almost half and start over again because it was turning out too big.
Are you wondering how to open it?
You slide over one ring and then you can get into one of the pouches, and you slide them both over to get into the other side.
