Third Sock Syndrome

Finished the first knot stitch sock last night. Here it is:

Then I started thinking that I should have done a 1x1 ribbing at the top, and that led to thoughts that a tubular ribbing might be even nicer, so I've ended up starting the second sock with tubular 1x1 ribbing. I like Ysolda Teague's method best, shown here.

 

If I like this sock better, then I have enough wool to knit a third !!! sock to match it. Yes, sometimes I wonder about my sanity.
