For those of you who soak your brush,
Do you soak just the bristles or the entire brush?
I just got a badger brush and I don't want to mess it up, but I'm having a hard time keeping it propped up in my mug while soaking due to the soft bristles. My boar brush used to stay up just fine. It seems like I've seen tutorial videos where guys have their entire brush sitting in a sinkful of water.
What do you think?
