I am having a hard time deciding if I should put my logo/website on the back of custom stationary, I do have it on the back of my greeting cards but not invitations. What are your shop policies?
I absolutely do not put my logo on custom work. Clients pay me for their design, printing, etc and it should represent the best work I can do--but for them. I always include a business card (or two) in the box so if they're happy with my work they can share my contact info easily.
The one exception is sending out samples--then I do label my work.
