How do I keep track? I have lists, and more lists, and even more lists.
I did keep them on the blog sidebar (and they're probably still hanging out there) but don't update them well. I joined a couple of UFO challenges this year, and made the list (as best I could) in my journal, then posted them/e-mailed them, etc.
I don't buy kits, so I think I only have one that a secret sister gave me.
I DO have a bunch of "going to do that project" material, but I have no issues with using it for other projects and eventually making a substitution for the original project.
My oldest UFO is either a dancing ladies applique that I bought at a quilt show (my guess is 40s, but it could be a little earlier or later) OR my mom's 9-patch, which is now QUILTED and the binding material is in the wash! Oldest UFO that I started? maybe a flying geese quilt from the mid-80s which is likely to never get finished :)
