One of my in-between-project projects was to reorganize my tools, which had gotten out of control due to all of the projects split between the two houses. I setup a staging ground in the lake house, and piled all of the tools and building supplies into categories before organizing them.
After that was done, I purchased and assembled some additional storage cabinets, as well as clearing space in existing cabinetry and adding some shelving.
After that, I placed all of the tools in their place, in a logical order, and labeled all of the cabinets, shelves, and drawers with a label maker so that I can easily find things in the future and not constantly re-buy building supplies that I already have.
After everything, both garages, plus the guest house, were completely clean and clear of piles of tools.
