My family has a serious love of peanut butter. My husband considers himself a master at creating the perfect jelly to peanut butter ratio. Therefore I have a steady flow of peanut butter jars. I use them all the time. I love my jelly jars too but these plastic jars are just awesome for holding a wide variety of items.
They are useful water containers for water coloring because you can take it anywhere and you can use the lid to create a wash. If you add a rubber band to slip in your paintbrushes, pencils and other tools you have a nifty watercolor kit.
Perfect Snack containers for holding my vanilla macaroon granola.
