The Dreamblade web page has a downloadable, large format board that you can take to your local print shop and have printed on vinyl. My local Kinko's quoted me $18, so about have price of the retail ones.
I'm a dope when it comes to this PDF stuff. Do you bring kinko's the file or the link and they pull it up on their computer?
The mat is in parts. How is that not visible after putting it to vinyl?
Sorry so Dim...
