I would think that with that shade it should be simple to spray glue flannel onto it a little at a time so you could smooth it out a you go making sure the roll is covered. I would not want to take the shade apart if you don't have to. My design wall is portable because of need but I can put it up on my curtain rod. I just attach skirt hangers to it. Actually, I have a few so I can fold them and put them away.
