Pottery With a Purpose at Mainstage Brewing Gunbarrel - Register Today!

Saturday, June 27th, 2026 ~ 2 PM - 4 PM

Join us for Brews & Fun with a Purpose!

Pottery with a Purpose is bringing clay and creativity to Mainstage Brewing for a fun beginner-friendly pottery workshop. Guests can sip a drink, get a little messy, and learn the basics of hand-building while creating their own one-of-a-kind pottery piece. It’s the perfect excuse to slow down, laugh with friends and make something with your own two hands.

Not only are these workshops a great way to practice mindfulness & therapy, but every purchase also gives back. $1 from every ticket sold is donated to nonprofit organizations supporting mental health and community care.
