Hang the Sunshine Window Panel in any window and watch the beautiful colors glow throughout your room! Each Paul Sahlin Tiffany stained glass creation is carefully cut, hand foiled and then soldered together by talented craftsmen. Because each piece is made by hand from art glass, it is unique in color and style. It may have some blisters, seeds, lines, and variations in the surface. These are not defects, but are simply characteristic of hand crafted fixtures and stained glass. All lamp bases are zinc with a hand polished finish. All fixtures are U.L. approved. The unique designs and exceptional quality of these stained glass creations makes them a welcome addition to any home.
