I know this is a long shot, but I thought I'd try. My grandmother want's a new mantle to match the floors in her home. Unfortunately for my great uncle, the one making the mantle, the floors are fake chestnut, and they live out west in Utah where that wood is even rarer than around here. He's asked me to help him source 4 8'x8" 4/4 boards, though the mantle will only be 6' long so there is some flexibility in the widths and lengths of course. I'd be happy to pay a fair price if anyone has some they are willing to part with from their lumber hoard, thanks for reading this.
