I spent yesterday redoing all of my kitchen cabinets. I put items, food stuff, in Tupperware vs just storing the empty Tupperware. Emptied a lot of boxes! I just cut off the description from the box and taped it to the outside of the Tupperware. Sure opened up more storage space! And put all of that Tupperware to use. I found a few duplicate boxes of stuff too.
I moved a lot of dishes and cookware to more accessible cabinets. I hate corner base cabinets because they are so awkward to get things out of and put away. No, i don't have a laZy susan...had one...hated it! Spent too much time putting items back on it after I would give it a spin! Takes up too much storage space too. i just stored items that i don't use often in the lower corner cabinet.
