I keep a notebook that has lines on the front of the pages and quarter inch grid on the back of the pages for all my quilty ideas. I used to carry it to meetings of course but now it just stays in the sewing room. I also keep it beside me and when I am cleaning or straightening my room I run a tally of ufos. One of my Guilds has a Get R Done challenge where you can list 20 projects you have started and would like to get finished the next year. The Christmas party is a huge giveaway for those that have completed a few of them and their name gets put into a pot for drawings. The past few years, there has been a sewing machine as top prize. The best idea I have heard is a friend that puts photos and dates of all her finished quilts in a photo album. Love the idea, just haven't done that.
