First time using a heavy wool fabric. It's a little bit difficult to work with; doesn't lay flat or crease after ironing so it's challenging to hand-fell the seams and fold the pocket pieces.
Made a separate band out of canvas for the armhole. That way my machine doesn't have to try and pass through 7 layers of thick fabric, and it keeps the armhole seam from puckering so much.
This vest was also a test of my grading skills. This one was supposed to measure 44" across the chest, ended up 45 1/2". But I do feel pretty good about my sizes 36, 38, 40, and 42.
