We have an existing patio paved with three rivers flagstone, and we are putting in a small patio on the other side of a walkway that we wanted to have match... But we are hearing from suppliers around here that the product is no longer available as the quarry was shut down. Anyone know if there is still a source for it somewhere, or enough old stock for us to finish our project? (This'll teach us to not do all the stone work at the same time)
