First step--- lay out all of the containers and then dump the lids in the middle. I totally should have hired a 5 year old for the next part and they would have loved the matching.
After matching, I stacked the containers to condense them and thought about their purpose and where I would store them. The containers with blue lids are from IKEA and the lids fit multiple size containers so I don't have to try every lid I own to find a match. The pile with the red lids are very substantial-- lids fit tight and I can drop them without them busting open. The green pile has a different size lid for every container-- not working for me-- GONE. The pile on the left are the cheap "disposable" containers. When I thought about what I use those for, I realized that their purpose is generally for being given away during a Soup Swap and I only use the one quart size. Bye bye to the rest.
