Teen, I had to laugh at your WIP situation...I always have at least 4 WIPs in addition to UFOs... it’s your call when they become UFOs. For some folks it’s when they haven’t been worked on for a year or more for others it may be longer or shorter. I have always put my UFOs in plastic scrapbook envelopes which stand up in a cardboard box under a table in my studio and those were always my “official” UFOs- most stay there for a year or more before they get finished. I also have a few long term UFOs that are so well stored (hidden might be a better word) that I tend to forget about them unless I run across them while reorganizing my studio. So I thought my system was working pretty well until I discovered some WIPs that had gotten buried under other more current WIPs....who knows what to call those, they've gone for months without any work on them because I didn”t see them in the chaos- maybe they’re now UFOs due to the hiatus....
