I've made about 25 crocheted coat hanger covers -- My mom was in the hospital, and to take up time, I just crocheted! I could make one an hour, without interruptions.

I've also made quilted coasters and table runners and Christmas-themed place mats. -- All the ideas on this site are making me wish it was June instead of October so I would have more time to do new projects!
