Here is my minimal cable project, the Gathered Pullover from the current (winter '07) Interweave Knits. I used Knit Picks Merino Style yarn in "Moss" and US size 8 needles (5 mm). The cable detail in the middle is the most fun I've had knitting cables and provides some shaping in what's otherwise a long tube. All in all, a great knit. More photos & details at my blog.
