Endast

Hello, I'm trying to make a Buff Coat with two layers of 5-6 oz milled veg tan leather as padding under SCA armor for the torso and the elbow. I will be using the 1630 doublet pattern from Reconstructing History. However, my problem comes from sizing instruction selection due to the instruction being based on a single layer of cloth. Would the sizing change? If so, how much bigger would it be?
