Muslin vs lining.
Muslin is really handy for mockups because it's cheap and easy to work with - the butcher paper of the sewing world.
But it lies. It doesn't drape well. It wrinkles in weird ways. It bunches. It tries to tell me the draft isn't right even when I've triple checked all my numbers and can feel the fit for myself.
Trusting my math and experience enough to actually cut the fashion fabric is always a leap of faith.
