Wow, Kit, and I thought I had it bad!

I haven't quite had that much trouble yet....
That actually crossed my mind. There is a "heavy duty" spray starch available at Target that I could buy and take with me.
The serger....I don't know how to thread it either. XD It's my teacher's machine. I just know how to use it.
I sewed together all but one side seam of the skirt today, and my goodness is it huge.

I'm going to love it when it's done though.
I have to add the side seam pockets (yay, more handsewing

) and the waistband, and then I can work on the hem facings.
I noticed there are a few pin-sized holes in the hem of my green skirt, unfortunately. It was prone to them, since the waist was a little large due to the misplaced hook, and it slipped down, sweeping the floor a lot. This skirt will be around two to three inches off the floor, so I won't have to worry about it as much. I can sew nylon horsehair braid into the seam, though, with a tiny width of the edge sticking out of the hem to take the wear and abuse of dragging on stairs, etc., right?
How wide should the hem facings be? I know period ones were sometimes 24 inches high, but that would make the skirt insanely heavy, especially with the cotton duck. Maybe 8-10 inches as a compromise?
Also: does anyone know of a cheap source for the wide, stiff horsehair braid (6-8 inches) besides Farthingales CA? I don't want to have to deal with the duty fees, and the L.A. store doesn't carry horsehair braid.
Thank you!
