DIY shaving brush. I have a 30mm finest two band badger knot, actually gluebump is making it 32mm just where it leaves the handle, wondering about loft. With my 24mm knot I used 48mm, on a 26 went for 52, so is it going to be 30/60 in my new handle ie always adhere to 2x? What is the the loft on your 30mm brush? Lower? Higher?
