Box Pleats just keep on kicking

It's been the Year of the Box Pleat Valance aka Kick Pleat Valance- you choose.
I like Danny's take on the style: he likes to put a contrast insert in the pleats, and leave a space of 1/2" - 1" between the main sections to show off the contrast.

Especially with thicker fabrics, like these, the fabric on top of the board may bulge upward where the pleat fabrics are layered.  There are a number of ways to deal with this; one is to layer cardboard tacking strip in between the pleats to build up the center portions of the main sections so they're even with the pleat areas.
