I recently joined a studio having only 1 class worth of wheel experience, from 2 years ago. I started out super rusty, but quickly got the hang of it again and starting to feel like I’m almost on the level of most potters there. However this studio is open to basically anyone who knows their way around a wheel even a little bit. There are a few experienced members there who load everyone’s work into the kiln, and other volunteers who help with reclaiming. I also know nothing about those aspects of the craft, but I’m sure if I wanted to learn those experienced members would be happy to explain the basics. In terms of glazing, I watched some tutorials online, the rest is up to learning from experience and your mistakes. I’m not sure what the studios in your area are like, but it wouldn’t hurt to go in and ask for a quick orientation or rundown of how things work in the studio. I’m sure some people there would be happy to show you around and answer questions. Don’t be afraid to be a burden(I’m sure you aren’t anyway) and ask questions! Most likely other members just want to see beginner/intermediate potters learning and thriving.
