An idea for organizing that has worked for me is to use a recipe card for each box or tub to list (in pencil so you can add or delete fabarics over the years) all the contents. Then label each box ie: 1,2,3, this I write on the top of the recipe card along with which shelves or closet I have placed the bos. Like Guest room closet, box 1.I then put the cards in the frnt of my recipe card file.
That way you do not have to wander around looking at each box or lifting it to go through it. I also did this with my Chhristmas decorations so I remember to get all of them out each year.
