Black Opal Wissmach Stained Glass Sheet - 8" X 12" (.67sf) By Stallings Stained Glass

The picture is a square which looks like a 12" x 12 ". However the details do nor match the picture. It is 8 " x 12". This as false advertising. Was disappointed with the dimensions that I received. Must have picture match the details in dimensions in the details.

Loved the color contrast and ease of use
