The thing that gets me to finish stuff is quilt shows. We have small quilt clubs near here that have a show once a year, and when the small communities have their "Days" in the summer, many times they ask for quilts to hang. I can take the same quilt to several of these, but they are a good incentive to finish something. I also think I have to finish something that I want to donate. I don't like it that the quilt is sitting in my sewing room and not keeping someone warm.
That said, I have plenty that are started. Whenever I see a block that catches my eye, I have to make one. Especially if it is something challenging. Someday, all these orphans will go into an orphan quilt. SOMEDAY!
