Thanks. Yes to all questions.
Yes, I learned this pattern when I was 10 years old. Be happy to help out if you have any questions. Socks are really just 2 tubes connected by a heel... with one end shut off for toes. My hubby likes to wear thongs with socks (i.e., flip-flops) so I once knitted him a pair with like a "thumb" for the big toe. Worked out okay, looks totally weird!
And yes, I play the Celtic harp. In that photo, it was for one of my co-worker's retirement function. Should see me in my goofy St. Patrick's Day over-sized Irish hat.
