Since he only has a long weekend, a single session makes the most sense. I took my dad to a one-time pottery class in Austin at Pottery Studio 1 when he visited last spring, and it worked out great. You book online, pick a time slot (they run from 10 am to 8 pm, so it’s easy to fit around other plans), and show up. The regular class is $90 per person, and there’s a version with painting for $130 if you want to decorate more. Each of us made a mug in about two hours, and my dad, who claimed he had no artistic talent at all, ended up enjoying it more than me. One thing to plan for: pieces get fired afterward and take two to three weeks, so ask if they can ship your brother’s piece or just pick it up for him and mail it yourself. That’s what I ended up doing for my dad.
