good topic, this really depends on the nature of your shop. I can understand why jewelry crafters would hesitate on sharing, they would'nt want exact duplicates of their pieces out there. but I give info freely, after all most of the stenciled sign makers buy our stencils from the same 6 or 7 stencil makers anyway, but it's talent that really sets your shop apart from the rest, not everyone can buy a stencil and just start producing quality primitive signs, I've been woodworking for 30 years + some techniques just come with practice and experience..
