Get the cards! I got some made about two years ago, and started putting one everywhere I could, lots of book store and art supply stores have bulletin boards for that sort of thing, and I got a ton of emails and calls. Some where just; "Hey great work!" emails, but also I did get some DVDs sold
(shamlesss plug- Steve the Vampire DVD's 6 bucks! PM me and I'll get one out to ya) and a few commissions to build puppets!
I'm a big fan of guerilla marketing... I even hit local library’s and put a card in all the puppet making book their, etc...
Well worth the investment... Staples even had a set up wher eif you do them there they put it on a Flash drive that you can save and bring to any Staples and have more made without any hassle!
