I'm so excited, I just joined my first official blog knitalong - Fall for Cables - and am about to start an actual (although itty bitty) cable project ~ this Owl Dishcloth. If that goes OK, I will go on to try something more advanced. I'm starting the owl this morning, and no, I'm not just trying to avoid seaming the rabbit. (Much.) (What? I can do BOTH.)
I also found a couple of cable patterns HERE. Some of the ones I like are: Twisted Cable , Alternating Cable, Single Cable,Tight Braid, and Five Stitch.
Also thinking about a horseshoe cable, or a braid cable, from the Knitty Gritty DIYnetwork site.
Since I am just learning (and indecisive) I might do a sampler sort of thing.
