So in doing a search, I didn't see much.  Maybe there's stuff out there but thought I would post for info.  I didn't want to tear into my ceiling tiles to hang a valence so I found some fairly cheap hooks on Amazon - about .50c/hook.  All it required was a wood frame to hold everything.  My plan is to hang vinyl flooring strips as the valence as I saw in  Chris Adams' Post.  Mine is probably not the best way to do this but it's working for now.  I shaved 2x2 x8's into thin strips and stacked/glued for the curved sections.  I'll probably go back and replace the wiring hangers for a neater appearance..

Frame is 1x3 L attached to backdrop with 1x2's extending out
