oooh! Those DropsDesigns are great!!! My niece saw a really pricey knit cable bag this summer (60% off it was still about $70!). These would be great for Christmas presents - not to mention a good way to practice cabling! Thanks for the links, MamaBear.
For an even simpler pattern you could do a k6 p2 rib with cable every other knit section, and cable row worked every 8-10 rows. I think you can do it. When you see something you like, it's time to experiment.
Round and round we go, where we stop noboby knows.
