I just watched the Working with Rolled Edges video lesson, and it brought up a question I have long had: why does Bullseye sell sheets with rolled edges rather than trimmed, square-edged sheets? To me, it would make more sense to sell something that doesn't have waste built into it. Then the price I pay is for the glass I actually use. And it seems more efficient (and "green") for Bullseye to trim and recycle the glass at the factory than to ship it around the world, and have the end users deal with it.
Plus, I love to pull out a sheet of Tekta and start working right away, rather than having to trim 2 edges of each piece.
