At Borders today I got into a conversation with another knitter (isn't if funny how we 'find' each other). She has actually knitted the coolest socks with that pattern. I mean, really really cool. After the holidays she's going to teach me how. She also has her own sheep, and llamas, etc. She does EVERYTHING she can to have the best wool.
Your square is really nice, and it's good that you had fun with it.
