We also give the casts back to the patient - I tell the patient to keep them for around 3 years. Obviously depending on their age and foot conditions.
I once saw a pod who had a good system for keeping their casts. THey had them all filed in alphabetical order under their house, and kept the most recent casts at the front, and the remainder at the back. I think they kept the casts for about 3-5 years.
It seems like alot of work to me! Just give the responsibility to the patient! Tell them that they make good doorstops and paperweights!
