We all have different filing systems for our papers. What works for Linda Case are these 12 x 12 files. She sticks a 6 x 6 sheet protector to the front with a list of the names of the papers and has several of these. I use large bins in a cabinet so they are portable. I used to have the rack system, but with running crops, I needed to be able to load and go.
Now I am re-thinking this and my back will thank me!
