I realize this might not be the most appropriate newsgroup for this query, but hope someone here can steer me in the right direction. We want to build a bench around a large old tree trunk (we just had the tree cut down to about 14 feet and want to plant vines around it). I distinctly remember, some time ago, seeing a catalogue that carried the joint hardware for those hexagonal or octagonal benches that fit around trees; you supply your own planking or two-by-fours -- pretty much like the joint hardware for raised garden beds etc. I can't find it anywhere now. I've ransacked all my catalogues and gardening magazines, to no avail; they all either sell entire benches or kits that are fairly expensive. Does anyone know what I'm talking about and can they point me to a source?
TIA.
