If you are just trying to keep it neat and tidy, then just down works great. But if you really want to make it look bigger then you can comb back up and out. You can also comb the underside forward and out to form a ridge almost like a fake jaw line. If you look at some of your better Santas you will know what I mean. Of coarse you need a fairly long beard before you can really notice a difference.I'm assuming that apart from the moustache, which I sweep to the sides away from the philtrum, that the rest of the beard would just be brushed downwards?
