I’m cleaning out my shop and I have a lot of stuff. What’s working for me is to take a stab at how much of one kind of thing I have (that I want to keep), put it in a nice clean cardboard box, write on it in big fat felt marker what it is and face the label out on a shelf. “BOAT PARTS” might work for you. With everyone getting Amazon deliveries, it’s not hard to get an assortment of good boxes and “put like things together” one of my wife’s great sayings.
Hope this helps. Lord knows you help enough people
