Before I knitted the mobius (or is it mobii?) scarves, I checked out several places online. They were about as clear as mud to me!
Bordhi's book is somewhat helpful. If at all possible, check out any shops near you which might give classes in this. Going to a class and actually seeing this done helped me tremendously!
I love knitting these scarves/shawls and seeing the perplexed look on some peoples' faces when they can't untangle the half-hitch knitted into it!
