Just what is wrong with looping it and pulling the ends through? Very European, I think. (Allright, so it's my personal preference as well...)
Actually, I don't like to tuck it into my coat, so it's a great way to keep your scarf on your neck on very windy days (I live in Michigan, so we have many...).
I like my scarves to be about 60" long. The nice thing about scarves is, when it looks done, it usually is. I have a very "Star Wars" approach to knitting. Just feel the force. The scarf will tell you when it's done.
Jeepers...I am a huge dork, eh?
