We basically had a private stained glass lesson with Theresa! My mom and I are not experienced with glass in this medium. Directions were easy to understand, we learned proper technique for cutting glass, grinding the individual parts of the final piece, adding the copper tape, and how to solder the pieces together. Did I mention the shop doggo?! Lotus is the sweetest lil baby with the most amazing blue eyes!! We enjoyed our experience so much we ordered some kits to use for our Christmas Eve family project!! 12/10 would go back for another class!
