I got a video to actually show me how to use an airbrush Michelle.  First step in the right direction.  I worked on a couple mounts I have out hanging in the shop that are there for practice and repair.  I had some old refurbished mounts.  All fun to play with.  Sort of like a junker car taken to the high school shop class.  Anyhow, having fun with it.  Probably won't be doing fish anytime soon.
