Hi! Welcome to KH. David's done some impressive knitting and it's great that he got you to join us. The best place to start looking for patterns that I know of is www.ravelry.com
. It's free to join. I've not gotten spam or any other problems from joining there. A search there for men's socks, 2- and 4-ply yarns yields this
. You can narrow it more by top-down or toe-up and other things too. My favorite so far is the Lifestyle Toe Up Socks
because I can do just about anything I like with them and don't need a pattern. Have fun! Let us know what pattern you choose, please.
