Sunspots is a two-for-one type of location. You can shop and see live entertainment at once! The store has a wide variety of items...and a wide variety of prices...for the hand-blown glass items. One of the coolest things that I have seen there for only $10 is a glass ring holder (to put your wedding rings, etc. while gardening or cleaning house).
In the same building you can view artists at work blowing glass in the hot shop. There is typically a small crowd gathered around the window at the back of the shop. It's amazing to watch!
Finally, upstairs there is a gallery of fine art - of course, all glass! I believe most of it is for sale as well!
