Hi Ladies!

I'm Elaine and am just getting ready to start my socks. I am so excited to be a part of this knitalong. This will be my first knitalong, so bare with me. I have only been knitting about a year and a half. I fell in love with these socks the minute I saw them on Knitty.
I have a question already.....lol.
I was reveiwing the pattern and understand the hourglass cable. But when it coomes to the "Oh so simple looking "A", "B" and "C" cables, that's where I'm stumped. Do I do the cables the same as the legend for the hourglass cable? Or what? I don't see a legend for them. This is probably a stupid question and probably so simple. Sort of like if it was a snake it probably would have bit me several times already!
ANy help on this would be greatly appreciated.
