Hi Diane,
I know there are a few patterns out there for these types of scarves, but maybe you'd like to design your own. You could use a stitch dictionary and figure out what stitch you'd like to make.
This site has tons of stitch patterns:

You could figure out a border if you wanted to and then do the stitch pattern in between.
Just a thought...
