Obviously, a CW surgeon should have a stock of bandages. Can these bandages be made at home or is there a source they should be procured through? I hope they can be home made and packaged at home... Instructions?

I am new to Civil War reenacting (have done some frontier trapper) working on getting started as a surgeon in Gray and hopefully to be able to galvanize. I have been watching this board and it looked like a good place for info. As an old Navy HM who stayed in surgery for many years, I think the choice is a great one.
