2009 0819 lighter circular cast-on two similar ways (knitting)

There are two circular cast-ons that I've seen floating around on the web that I like to use. The one I use ends up being the one I remember at the time because they are really similar. There's the version in TECHknitter's blog called the disappearing loop method, and there's the one from Eunny Jang's retired blog called the lighter circular cast-on.
