Window treatment

An upholstered valance with stationary panels and tie backs. it was done in a girl's room.
I had to make a template to fit in a triangular ceiling.
The mounting of the whole treatment was a bit of a challenge.
I installed a board behind the upholstered cornice so, I can mount the panels inside it but, first I installed the upholstered cornice to the ceiling by using Angle brackets.
