I got the wall done today. 2x4 framed with particle board backing then the insulation then flannel. It has a 2x4 holding the bottom out 3" I think it turned out ok, it works well my string quilt on it. In the future I want to make it free stand in the floor and have the backside finished as a design wall too.
