Hubby's socks

My first pair of socks, knitted on circular needles, and I found knitting them great compared to dpn, they knitted up fairly quickly too it seemed, so now thats something new I have learned to do, My other half said they are great for his work boots, and very comfy and that he want's some more, so it looks like Iam going to have to learn how to do the 2 at the same time then, oh it should be fun!!!!
