i've only done it twice. i want to try it again. to me, it's more formal or dresier. it adds to a blah quilt. i did it on my sons white on white, and on a lap quilt for myself, a red and white quilt.
Your quilt is so stunning, personally, i don't think you'll need it. it's a stand alone quilt to m e. very precise and pretty. I love your points too!!!
