Why are gel sheets 20x24? Is there no other way to market them so that there isn't wasted gel? It seems like no matter how I make full cuts, and piece together one or two extras out of scotch tape, there are always scraps left over. I understand with all of the different frame sizes and applications it can be hard to come to a standard, but we're definitely entering the age of waste reduction. Even if it's not possible to reach a standard, why 20x24?
