Sinful? What Sin? It's YOUR quilt now and you can just ignore the sirens of the quilt police and do what makes you happy.
Lots of these suggestions here sound lovely, but it's up to you to decide what is best for your quilt. Me, I like the quilt robes so that I can keep them in the front room and show them off to visitors!!
Show us the final product, I'll bet it will be lovely.
