I'm with canoePam. I get frustrated and confused if I have more than one active project and if an emergency one pops up, I put the active one in the WIP bin, get right back to it once the emergency is completed. I also have a bin of planned projects which can consist of pattern, fabric and everything I need for the complete project, or sometimes only the pattern. And, I admit I have an UFO bin which I try to keep at no more than 3 or 4. I can't abide being frustrated and confused. One night at guild everyone had to tell how many UFOs they had. When one lady said 65, the room was stunned to silence.
