Rookie's question- I'm making a down quilt and looks like i can't turn the quilt inside out to sew the edges first and then buffles or it would be to tricky and not worth my time. If i sew the baffles first, what seam should i use on the edges of the right-side-out quilt that would be strong and prevent fraying? I found this on the web, should i use this?

Thank you!
