The knitty article is what I tend to use for reference. I have a detailed tutorial from a pattern I purchased -it's the same thing, but I think the knitty directions are written out a little more clearly.

I would bet somewhere between the toes that worked right and this toe you lost a step or so. I've done that in the past "I know how to do this, la la la...wait...o_O" :D

Good luck on the next one! You'll have to let us know how it works out for you.
