I'd heard for a long time that there was a woman selling her own weaving in Chapala but I'd never found her. But we finally did on Saturday. She's from Oaxaca and a lot of what she sells is her own work. Some things are not (and you'll know by the difference in price). I do recommend getting one of her hand-woven items.
She is near the new Maria Isabel restaurant (where you can get good molcajete) where the old Posada used to be at the pier, go east along the dirt road/parking for a bit. You'll see her work hanging to your left after the outdoor seating for the restaurant ends.
