I cataloged all mine in a spreadsheet, printed out a list, had them closed on shelves with the number on the end of the wood handle showing so I could find it on my list, then looked for the number of handle. I had the shelves with numbers so I had location numbers on my list and still couldn't find what I was looking for when I needed a mold. so I put them on peg board .The pic of my molds takes up a lot of room but at least if can find what I am looking for. and while looking for a mold i'll see one that i forgot i had, so that is helpful.
