My suggestion is not to bother bringing anything from home to work on at the crops once CKU starts. If you really want to work on anything, you can finish projects from your classes. But from what I've seen most people don't bother to do any scarpping during the crops. At the campus crop everyone is busy checking out all the dorms and layout entries. There are also lots of sponsor contests going on during the campus crop, many of which require participation not just a name drawn "out of the hat".
If you go to the earlybird crop you will need something to work on as this, from what I've heard cuz I've never even looked in on it, is just a space for anyone that's come in the day before CKU to spread out and work on their scrapping projects.
Some people did work on stuff at the celebrity crop and the commencement crop, but most either just stood around talking or went off to do other stuff.
