Summer Days is a gorgeous knitted sock pattern by Heidi Jokinen of Nordic Kitty Design. Its butterfly motif reminds us of breezy summer days, and the Viking Nordlys yarn it uses creates lots of options for color combinations. I've put together several awesome bundles for you. Each set includes one skein of the main color of Sulo sock yarn, one skein of Viking Nordlys for the contrast color.
