I have read that there is a program, Sure Cuts a Lot, that can be used with the Cricut Expression machine. How does it hook up to the cricut cutter? Does the Cricut Expression machine have a USB port? I would figure that you must hook up your cricut to your computer/laptop to be able to send the info from your computer to the cricut. Does any Cricut owner use this program and could explain exactly how it works.
