I've thought of the same thing, Iva Mae (my middle name is Mae, too). I'm thinking of trying this: On the last row, I'm going to go through the first stitch on the needle and the first stitch on the other end of the scarf and bind them off together. I think I'll give it a twist first so it's kind of like a moebius.

Anyone have another (better) idea? I'm all ears.

I found I liked doing it back and forth on a circular needle and I wondered if it wouild be possible to use a lot of stitches for the length and just do a few rows? Do you think that would work or not?

Sure, it would work. Only your ruffles will be vertical instead of horizontal.
