I've also been spray painting anything in my path lately.
So, when I needed something to put some fairy wands in that I made for a friend, I grabbed a pickle jar from the fridge, convinced Skylar she wanted to eat the last pickle, washed it out, and spray painted it. I was officially hooked on re-using jars.
So, when I had a ladies event at my house this week, I took a look at all my jars that are "waiting to be painted" and decided to do something with them.
I put a little sand from the sandbox in, added a tealight and some raffia, and voila!
I don't think we'll ever throw away another jar. :)
