Spreading the craft
A woodworker whose blog I follow said that he set up his woodshop in a storefront to expose passer-bys to traditional woodworking: they could see his projects in-progress as they passed by, and see him working.
I like that idea. When I retire I want to get a booth at the local weekend flea market and just demonstrate handtool woodworking. Maybe sell a few things -- but mostly just expose people to woodworking. Let people ask questions, get them interested in the craft.
