Has anyone experienced a valence falling off or coming lose? Got back from a recent 100 mile trip and the big valance (about 9 or 10' long) over the big windows had fallen off and was laying across the furniture. I looked and that big valence only had two little screws holding it up there and there were pulled out of the wall. Movement probably worked the screws lose and weight/gravity eventually took over. At least the valence didn't break apart when it fell. I'll get it back up there. I bought four more elbows to add to the original two (original elbow shown below). There is no way two was enough to support this big valence. During warranty I've had other valence issues fixed (coming lose from the wall). Just curious if I'm the only one.
