You will have a great time at the Tucson Quilt Fiesta! I have gone for the past 5 years and every year it gets better. Plenty of quilts to view and lots of vendors with tons of stuff to buy or just get ideas from.
I take a huge tote bag (I don't care for backpacks altho they are great for those who like them) and a very small purse/wallet that I can sling cross-wise over my shoulder to the opposite hip (taking in my regular purse is a pain). The little purse is big enough for cash and my driver's license. I like to use cash as it's easier than managing credit card slips and such and also gives me a hard spending limit which makes me really think about what I want to buy.
I'll be there on Saturday and can hardly wait! ENJOY!!!
