Calendar Next available session starts Oct 18, 2026 at 10 am
PGC 223 Put your personal touch on handblown glass pumpkins. In this introductory workshop, you’ll start with two clear glass pumpkins hand crafted by our glass artists and use an industrial sandblaster to create your own designs, playful faces, names, patterns, or other details. With guidance from an experienced instructor, you’ll transform each piece into something uniquely your own.

At the end of the workshop, you’ll leave with both of your sandblasted pumpkins, ready to display or give as gifts. One pumpkin has an opening at the base, perfect for adding fairy lights (not included) to create a glowing seasonal luminary.
