Pros : I recently used four sheets of Van Gogh glass in a class I taught. They were cranberry, silver, gold and a mixed blue green. The actual colors are as vivid as indicated, and the glass scores and breaks evenly and nippers also do a good job in working with the glass.
Cons : Cutting or nipping very narrow strips (maybe 1/8" or 1/16") too often result in the backing falling off.
Other Thoughts : The glass is a nice addition to regular glass.
