On day 6, I cast on the Vanilla Soaker (Ravelry link), thanks again to a random number generator. I worked for a couple of hours on it when I realized I was following the wrong directions, in my upset, I frogged it and decided not to cast on anything on day 6.
On day 7 (today), I went back and re-cast on the soaker, as you can see here:
I felt ok with skipping day 6 because I bought more yarn for Margaret's sweater/jacket and I bought some fabric for another project I'm going to do for the cast-on-a-thon. It involves Pacman. And it will be awesome. I need to get a few more supplies for that project, though.
