I took a break from my Branching out when I moved in August, and just unpacked it and put it back on the needles last week. It's getting to be a decent length, but I like really long scarves. I'm thinking I'll just block after 10 more repeats or so...ha. Like I said, I like 'em long.
I think I will have to stop when I run out of blocking space on my futon, or just be really clever about it - and block in pieces, lol.
