The way I do it: cut 2 strips of fabric, different colors, one about 1/4" wider than the other. Sew the strips together lengthwise, fold it with the raw edges together. This will make one of the colors fold over to the other side, this will be your flange. As with regular binding, align the raw edges of the binding with the raw edges of the quilt, and sew. Then fold the binding over the edge and machine stitch on the front, right in the ditch of the flange.

I have done this, but it's nice to know which fabric will be going around the quilt and which will be making the flange. It is the
wider fabric that makes the flange, and the narrower fabric goes over the edge of the quilt to the back. The rest of the flange fabric is underneath so you can't see it.
When you sew it onto the back, you will see only the flange fabric. Then it gets tipped to the front and most of that flange fabric is hidden.
