Where Can I Find ThingMarks To Print?

I know this is probably a silly question and easy to solve.

I have signed up for the Pilot program.  The server is up and running, and I have got my local ThingWorx Studio talking to the server.  It shows that I have three thingmarks to my name.  Where do I go to get the actual physical files of those marks so that I can print them?

Thank you for your help, and have a great day!
