I went to a Scrapbook Expo earlier this year - it was halfway between my sister and me, so we met for a sisters weekend. It looks similar to the one in St. CharlesI enjoyed it. I did take several workshops - the Fabulous Folds and the Cool Tools are the ones I see listed that I took, as well as an advanced pop up card one I don't see. I enjoyed them all, but the "freebies" we got at Cool Tools included some stuff I already owned (a score-pal!)
I spent more time in workshops than I did doing make n takes. I thought the vendors were good, and there were plenty of booths. I have not been to many of these, so I don't have a lot to judge by. I would not have gone more than 1 day, but my one day was pretty full.
