good for your!! I was not crazy about cables either at first when I started tried them!!! I even found them physically hard to do, to manipulate the neddles, the yarn, etc. But I have been liking them as I have kept doing them. I feel like I have finally mastered the movements and now it is pretty easy, no more finger/hand hurting or frustration. But it took time.
Still, it is so nice when you do your first cables, you think "oh, I did it, and they look good!"
