Flange binding can give such a nice finishing touch to a quilt, with that sliver of colour showing at the edge.
I do the same as Peckish .... except .... I hand stitch it on the front.
My reason for that is that with washings, I found that the narrow flange would shift around, so that it may lay flat or stick out or roll over onto the other part of the binding. For me, this keeps the narrow stripe of colour showing nice and even.
Sorry, I can't refer you to a video to see more, but I am sure someone will have a video link. Or perhaps Peckish's photo gives you what you need to see?
