I also like to use containers that used to hold something else in new ways...why throw away a perfectly good plastic jar and lid? This one on the left came with Pearl Couscous in it (which you should try if you never have) and now houses raw almonds that I like to buy in bulk at Sprouts Market.
Next time you need to organize, check out bargain places like Home Goods and Marshall's before heading straight to Target or Crate & Barrel. Or just check your pantry. You may find some very useful items in there just waiting to be filled up.
