S'Mom, I don't feel the picotin style would be structured enough for you. The purseket would fill it out, tho and help it keep it's shape......so.... but the handles are floppy.
The MM is plenty large.....I sold mine because it was too large for me. The GM is even larger.....all that said, the Picotin is very popular and one pretty little Hermes.
what about a structured Picotin - say indigo barenia? Or perhaps black barenia for s'mom!
