Your tile is wonderful! I understand your frustration about the pace of the pool build. I've felt that so often. Every time there's a flurry of work, I keep thinking it will continue. Then it stops. And time drags. And drags. And drags.
But then it picks up again, and all feels right with the world. It just seems to be the nature of things.
My experience with our glass tile, was that there was very, very little waste by the tile guys. It amazed me. So...... I had tons left over, and am still working to get them to come out to install it. So maybe whoever ordered it for you understands that better than I did (I would hope they do!). Did you have to wait for it to be ordered and shipped, or can they get more from a local tile store?
