I have hunter Douglas wood blinds from 2000. The valences have fallen off and no one seems to be aware of what held them on. I had thrown away the clips. The installer said the clips aren’t available anymore and duggedted I buy Velcro and magnets which I tried and doesn’t work because the mechanism is inset into the window frame. Dealing with hunter douglas has been beyond frustrating. They don’t seem to know what type of clips either. The valence does that have groves on the back as most of them do. Just a notch on each end. Anyone have any idea what sort of clips were used for the valence.
