I too am looking for something more interesting than a sc border. I think this blanket is so airy-fairy that it deserves something a little bit lacey for the border.
I'm not sure how I'm going to pull it off as they will need some creative adjusting, but I'm thinking one of these options:
Block edging

Or just the first two rows (the "ladder" bit at the top of the picture) of this one

I have NO IDEA what colour to use! Cripes! My original plan was to take my clue 6 colour and clue 4 colour and use those to make the border really pop! That is out the window now.
