Advice Needed! How to Finish This Scarf...

For Valentines Day, my sister made me a beautiful, knitted scarf (in my favorite shade of pink!) and told me to finish it off however I'd like. It did have tassles on it, but I took them off and have been fumbling for a more lacy look to add both looks and length to the scarf. I've been playing around with shell stitches and a  simple fishnet look, but I'm not sure I'm happy with any of them.

I need suggestions! What are your thoughts? Please comment!
