Rotating corner shelves for the pantry! Using lazy Susan for tea right now it is nice but my pantry has a support beam that goes down the corner. So not as assessable, but dose make the space more useable
Use a dish drain from the dollar store to organize plastic lids. Use a dish drainer to organize pot lids, or Tupperware lids in a cabinet. You can find them in all sizes now, to fit almost any cabinet, and they are super cheap at the dollar store!
