Inverted Box Pleat

Well, my apologies for the crummy photos.  I had the opportunity to show these two very different applications of inverted box pleats but no time to set up any sort of shoot for them, so here we are.
The top shows interlined silk, inverted box pleats to normal 2 1/2 times fullness, as well as contrast microcord and yummy silk tuxedo buttons.   The rings are sewn on, but the panels could be hung the rings with drapery pins.
The bottom shows very tiny inverted box pleats on an unlined sheer with 2" translucent buckram in the header.  The pleats on the sheer are there just to control the fabric on what are essentially flat panels;  they provide a good place to place the drapery pins so they'll be hidden.
The technique is exactly the same but what a different interpretation!
The bottom picture shows both examples from the back side.  There are a number of ways to finish an inverted box pleat, but I like the stitch-in-the-ditch method because it flattens the pleat out, provides a place for the pin, and gives some control.
