Has anyone used round slabs of wood for center pieces, cake stands, etc. If so, how did you go about inquiring the wood? Etsy has them for sale, but it seems awfully expensive for an untreated simple piece of wood. We don't own a chainsaw, or I would have my fiance do it ourselves. Has anyone had any luck getting scraps from a lumber yard? If you end up DIY, did you treat the wood in any way after cutting it? Thanks
