I'm also using the "junk mail" method too. So if you have any business card, send some this way and I'll be glad to put 'em out with my cards and orders.
Junk Mail Method: use the prepaid envelops and send back your business cards.
I'm sending them out in orders I get from my other shop (Tie Me Up Apparel/Shiny Things), using the junk mail method, and leaving them in places I go.
IF YOU ARE INTERESTED, LET ME KNOW AND SEND ME A E-MAIL TO firstname.lastname@example.org
