So my wife is designing our bedroom and wants a pelmet covering the top of the curtains. It is basically flat but then she wants an ornate top and then the whole lot painted.

Cut a couple of end pieces from 18mm MDF or 3/4 inch pine plank.

Cut a 1"x1" notch out of the front top corner of each end and join them
with a suitable length of 1x1. Pin & glue 6mm MDF to make the front and top.
