I use 1/2 inch painters tape and wright down all the film info.Just a small bit of tape to record film type,length, iso and attach it to the camera back, bottom,or case (It leaves no residue).When the roll is finished I then peel off the tape and attach it to the film cassette so the information is there when I develop.Found that this method prevents the "What in the name of god did I load on this roll" syndrome.
Should add that I use a Sharpie pen to record the information.
