Reader Michael Obadia asks the following question: "My business of designing and building custom shelving systems is going well. Except for one major detail: I no longer want to use new material for my projects. I live in Toronto, Canada and I am really trying to get a method for which I can purchase reclaimed plywood, lumber, or anything that can be used for shelving. Thank you all."
