What I do:
I supply a picture frame manufacturing company and other rustic wood-working businesses with old wood. They only want specific types of wood and i get in a variety. So the rest I sell to the public.
The majority of my sales are used to build picture frames, barnwood walls, benches, and similar projects.
I also sale old fence panels, old fence post, and benches.
If i missed anything important in my description please let me know
