For all my mason jar projects: An entire website with tons of different bottles or jars you can buy for thousands of different reasons. VERY inexpensive! Mason jars, cute little sauce bottles, medicine bottles.
Magic Eraser: cut a piece off and float it in your toilet overnight and no more toilet ring -clean window screens when they are still in the window- The website has a list of about 100 uses! Gonna try em! I do love my magic erasers!
