At first I was very matchy-matchy when I knit socks, but over time I realized that it is kind of fun to go for a more "mis-matched" look.
If you are knitting with self-striping or self-patterning yarn, the mis-matched look is super easy to accomplish.
The first sock is knit from your skein of yarn, as usual. The second sock is knit from the opposite end of the skein. This means you may have to rewind your yarn into a ball so you can work with the yarn from the other end.
Since you are already going for a mismatched look, there is no need to worry about starting your work at a specific point in the color pattern of the yarn. That makes life much easier.
And just in case you like these yarns, the first pair of socks is made with Patons Kroy Sock Yarn in Meadow Stripes and the second pair is made from Universal Yarn Wisdom Yarns Allegro in Apricot Air.
