If this heat makes you yearn for a free air-conditioned space, then head to Catalyst Ranch tonight to meet up with the Chicago Craft Mafia for their first annual Summer Shakedown. They, and 19 "friends of the family", are putting aside their glue guns, seam rippers, and scissors long enough to let you get a peek at what they've been making. We'll see you there between 8pm and 11pm. Right? Yeah! Dat's what I thought!
