Did you draw your taper lines...aka pleat edgelines on the tartan in chalk?

I agree, that's a good idea, and the chalk will brush out with a toothbrush. Don't use a dressmakers pencil, though, whatever you do! That doesn't brush out!

Just as an aside, I started sewing my California Tartan box pleat exactly as Barb has suggested. After meticulously sewing one pleat I realized that I could pin the thing in place and machine-sew the pleats ten times faster and the stitching would be invisible as well as half-again stronger.

So I did.
