I have been knitting for years and My brothers and father both love to hunt. Every year they go and put on several layers of cloths and get into their gear and go out hunting. One day my brother Shaun came to me and asked me if I could knit him a pair of men's long Johns. I told him well I don't know if I can knit one but you go buy me a pair of men's thermal underwear in your size and I will see what I can do. The first thing i did when he brought me the underwear is I had laid them out and cut the seams so I had piece's of a pattern.
