I have a thing for art nouveau and arts and crafts tiles, so I was drawn to this arts & crafts tile poster by Mindy Sommers.
From there, I discovered not only this beautiful Bell Epoch poster by the artist, but that her art nouveau stained glass art can be found on more than Zazzle products because the artist and her husband run Color Bakery.
The stained glass art works (along with many other works) can be ordered custom on all their products.
Of the stained glass works, the artist says:
People ask me if, when printed on glass, if they will light up. The answer is yes. They won’t allow extensive light as they are not transparent…however, they are luminescent and direct lighting behind them will give the artwork a beautiful ambient glow.
While Color Bakery offers hundreds of their own designs, they allow customers to upload their own images to be put on everything from scratch resistant porcelain floor tiles (that you really can walk on!) to artsy mirror compacts. And if you’re an artist, Color Bakery provides custom art printing for artists and photographers too.
Authors bio is coming up shortly. 
Thank you so much for the kind writeup and referral. I appreciate it very much!
