Gearing up for the Squam Arts Fair

We're excited to be joining an impressive list of vendors at the annual Squam Spring Art Fair.  I hear that Ravelry will be there (if you know the online fiber community, then you know that this is HUGE).

I'm making lists and gathering supplies for our little booth and am trying to figure out just how to take orders for shoes that have not yet been made.  Thanks to a brilliant suggestion from Maya, I'm thinking about bringing a huge roll of butcher paper and taking foot tracings on the spot.  What do you think?  Will people be okay with placing orders and waiting for a package in the mail?  I sure hope so.  Handmade to order is probably not typical art fair fare...
