maT, click on the first link, click on service projects, scroll to the bottom for a tutorial on how to make T.A.G. Bags. I think these are the ditty bags that would be tied to the side rails of the soldier's bag.
I like the thought of the traditional bedside caddy, but those would be more difficult to use with a hospital bad.
Perhaps one of our wise ones could combine the two, a tie on bedside caddy/ditty bag.
