I'm starting to make an x-kilt. Grandma just gave me an old industrial sewing machine she had lying around (i'm 17). Now, I have a small bit of extra gut (Not huge, like it discusses in the tutorial), and a very unusually small rump, to the point where my rump measurement is smaller than the measurement around my navel. If I change the measurements, to be around my pant line, and measure the fell from there, etc etc, change all the measurements to match, will it still work? Or do I need to do something totally different? I'm using black canvas if anyone wants to know.
