This was an experiment/wild hair last spring. I designed the bag based upon a pattern I found on the web, specified and sourced the materials locally, and then had one of my art students (who specializes in soft sculpture) assemble it for me. I think the total cost - if that's important - came to around $40, including labor and I had sufficient material left over to make at least one or two more. Important note: my student swears she'll never do one of these again!
