One common piece of advice for navigating the overwhelming Tucson show event is to pre-register for the big shows. Avoid the long lines and get the details on what paperwork they require when you show up at their doors (and even if you pre-register, you'll want all your papers with you at all times!). Most require a business license, others also require a jewelry professionals' membership OR proof of jewelry purchases in the form of invoices with mimimum purchase amounts. A hassle, but I guess its their way of filtering the crowds to just serious buyers.
Here are some shows who have already opened their pre-registration forms for Jan-Feb 2011 Tucson. Registration often ends early Jan, so don't forget to sign up soon!
