Organize (and Apply Finishing Touches)
Draw up a list or floor plan to ensure there is adequate storage for everything. Clutter often arises from insufficient storage space. Purchase the necessary supplies and get help to assemble/build/install what you need. Hint: In the planning process, allow extra shelf space for things in transit such as a box of donations, a box awaiting hazardous waste dropoff, a giveaway box, or perhaps bulk storage of household supplies like paper towels. Place things on their respective shelves and hooks keeping categories distinct. Label clearly for future reference and so that everyone who shares the space will know where to find things and where to put them away!
The tasks in Part 3 may take a few sessions. Beware, you may have to go through some trial and error before you find products/configurations that fit your needs. In the end though, an organized garage is well worth the effort. What were your goals and did you achieve them? Finding a home for every item? Reducing clutter? Clearing the floor? Parking a car in the garage? Being able to find things? Knowing what you've got? Uncovering meaningful memorabilia?
As a final touch remember to sweep the floor and dust off shelves before restocking! You might even consider washing or painting walls.
