I just love knitting socks. They're so portable, quick, and the entire rainbow and all its permutations are available in yarn. They can be solid stockinette, or lacy, or cable filled, or fair isle..... anything!!
I've put aside a pair I'm knitting for myself to start on a pair for my daughter's boyfriend's mom. She likes greens, and I think this will fit the bill nicely.
