Thanks for sharing this info. I’m new at this, so can’t offer help, but was curious about how artists collect payment. I know of one coffee shop in my neighborhood that offers space in their shop every Saturday for people to sell items. They charge $20 for a small table. And I’ve seen people indicate their info for payment. But I’ve never asked how the artist goes about making sure payment is received before the item goes home with the purchaser (if artist isn’t tnere).
