I think I'll go ahead and start ONE on my sz 0 needles. I don't have sz 1 fixed circs and the pattern even says dpn aren't a good idea. If it doesn't fit I can frog. For whatever reason starting these is very intimidating. I will have to finish my WIP socks before I start because I have to have the needles they're on.
Thanks so much for the help, both of you.
I should never overestimate my basic arithmetic skills.
