I need to make some valances to hide the head rails on some verticals and miniblinds. I plan to use the polyurathane molded molding. I made one and cut and glued on some returns to bring the pattern back to the wall. No problem, but I just made the returns as deep as the molding and nailed the completed piece flat to the wall. Same as you'd do a chair rail. Looks OK, no problem so far.
But in some instances i'd like to have the valance clear the wall by perhaps 2". That means the returns need to be deeper, and I can nail the completed piece to the wall either. I need to come up with a way to reinforce the returns, maybe some 3/8 baltic birch ply glued on, as well as a mounting method.
My thoughts at this point are angle brackets screwed to the wall and then screwed to the ply reinforcement. Don't really like that one though.
Any better ideas are wlcome!
