This is what I use.

Condor pouch

I hang it on the front of my shoulder straps on my chest. It is very convenient and holds all the little stuff. I also put my map and compass inside so that I don't have to stop and dig it out of my pack. It is kinda heavy, so I have been looking at ways to sew one out of lighter material. But man, the function is amazing. I love it.
