@Catherine: one strategy for increasing FSC use is to get get a lined out bid for your wood package from a typical supplier. Then send that bid to an FSC supplier, asking them for a bit that secures as much FSC within a given premium (for example 10%, if you are willing to pay a bit more). I did this recently on a new home project, and was able to secure timbers, CLT, car decking (roofing) as FSC. Plus I could get cabinets and flooring without much premium at all. So in the end, all the finished wood was FSC. On dimensional, I used Vaagen - not FSC but still decent restoration forestry.
