So I rebuilt the sashes, and they work much better.
The new layout:
I laboriously cut the monks cloth along the weave, serged the edges, and basted it onto the lining.
I gave myself a broader strip in which to enclose the piping.
They’re much cleaner with no loose edges to torment me.
In other news, I took a deep breath and finished the waistband and attached it to the skirt. I’m all done except the center back seam, which I will do today.
I pinned together the waistband in the back and tried the thing on. I am not at all pleased with the results. The waistband is a marvelously beautiful piece of work, but it’s too bulky. I’m going to have to play with it more, especially this weekend when the Old Men meet to put together the labyrinth for the first time and test drive the ritual.
And no, I am not posting photos of the skirt in situ, as it were. You will have to attend a Burn to see that.
update, 9/12/14: After working with a couple of entirely new designs, I revisited my finished skirt and decided to try just cutting off the top three inches of the waistband, i.e., the floppy, un-rollable mess. Et voilà, it worked. The result is clunky in a really groovy neo-Phoenician way. I think the team is going to approve.
