Out of desperation I've been doing a combination of what you guys are. I write a number on a box and then list the number, location, and contents on a handwritten list. Plan is to transfer the list to a worksheet but I haven't gotten that far.
This is what I did.I transfered everything into a spread sheet program.I was then able to print out a compete list of what I have and where it is.It's nice to be able to bring a copy with me to the shows so I know what I have and how many I have.It took awhile,but it was worth it.
