I just finished a pair of basic socks for Mom's 84th birthday. The design is just a plain old pair of socks, nothing fancy. Mom is old school... not old, mind you, just old school.
Things in her life need to be functional and simple. So, I knit her some plain crew socks in this gorgeous hand dyed yarn from a shop on etsy. I think the rich color brings a little class to this old school, plain Jane pair of crews.
