Long story short, these are my grandmother's birthday socks. The yarn is Madeline Tosh Vintage in tart (one of my favorite colors!). I knitted myself a sweater out of this yarn earlier in 2013 (see photos below!). When my grandmother asked me to knit her some socks, this yarn immediately came to mind and I cast on right away. She recently received them, and by all accounts she really likes them!
I'll catch you up on other knitting stuff later today, most likely. But now, I really ought to try to get back to sleep.
