Summer Decorating

Ok, so my favorite, cheapest, summer decor item is....

a Mason jar.

Or more specifically, a Mason jar with a tea light candle.

A bunch of them, in different sizes, on a big piece of mirror:

A couple on a windowsill:

Or lined up on a mantle:

Do you have a simple decoration item that you find shows up in your home over and over?

Please share with me!
