Rob, depends on how my fire is doing, I like to keep my smoke cool so I have 6' of pipe on my stove before enters hides, I would say today I had 1-1/2 hrs per side. I just keep checking in a hole or a spot where sewing isn't good, for the color I want, also like to see color bleeding thru from inside to out then flip an do other side usually a little less time.
