Pros : Ever since using this glass for water lily pads, I now keep at least 3 pieces in my stock. (Note: I create mosaics, not stained glass). When held to the light, the light green portion allows light giving a nice contrast to the dark sections.
Cons : NONE - even with the mottling and uneven texture it cuts easily
Other Thoughts : Best to buy in person if possible. I've received perfect pieces and then times were the greens are blurred rather than mottled and have to use them for other nature scenes. Also good for turtles, frogs, lizards, and alligators if you like to create animal scenes.
