The Shadetree Stained Glass Studio has one of the best stained glass artist in the country (Penny Kristo). Penny has created some of the most beautiful custom stained glass windows and has a special way of somehow seeing the vision of her customers and creating exactly what they want in their custom stained glass project. Penny also provides classes and training in the art of stained glass for people of all ages. Penny's son Jeremy also works at the studio and has become very skilled in restoring old church stained glass windows which is extremely difficult and very time consuming. Visiting the studio and talking with Penny and Jeremy has always been a highlight of our vacations when we go to Petoskey, Michigan. The quality of the stained glass in Penny's shop is spectacular.
