I have the Cables Untangled and the Vogue Sticthonary one and I am completely in love with Cables Untangled. There are patterns in the book - for clothes & home - and also many cable stitches in the back that aren't part of a pattern.
Although, with $60, you could get both!
I've not seen the Viking Knits....but I know others love that one too.
I'm being super helpful here!
