The scarf I made last year for my beautiful bellydance teacher
Make 9 squares of 6 rounds, 2 squares of 5 rounds and 4 squares of 3 rounds. Join them the way you like. I made this way but you can do all the squares of 6 rounds, and more squares if you want a longer scarf.
I also have put some fringes, that are very easy to do, but I don't know how to explain in in words! X( Just take a thread long twice the lenght you want your fringe to be. Take 3 threads, fold them in half and use the crochet hook to make the top of the three joined pass into one of the holes of the trim, then make the 6 "tails" of the threads pass into the top, and pull.
