I might need to take a break first, though -- I started one of them today, hemming some jeans, and promptly sliced right through the jeans much higher than I intended, ruining them. Argh. I measured once, rather than twice, before cutting. I know better, but I was tired. So finish the re-org, then take a day or two before actually starting on the various projects.
The basement's been a mess for a long, long, long time, and when I am less tired, I will undoubtedly feel a deep sense of accomplishment.
