I bought a skein of this sock yarn. It's Schoeller Fortissima/Socka 100g 4-ply Sock Yarn 1776 Stars & Stripes, and when knit up it becomes red and white stripes with a stripe of blue with white "stars" in it. When I first saw socks made up with this yarn I just had to have some.
It was out of stock everywhere I checked. So, I looked for it on eBay, and voila, found it in an eBay store that is actually located relatively close! I could have driven over to the store, but it was cheaper to order it and have it shipped.
After searching for an appropriate pattern for this yarn, it seems like most people just do a plain sock to let the striping show through. Since I'm not going to do my Anni's pattern this month (it's a two color pattern - beautiful, but I just don't want to mess with it), I decided to do my patriotic socks.
They should be finished by the end of April, and I can wear them to my family reunion over the 4th of July weekend. It will be hot, but my feet will be full of the spirit.
