I just discovered that you can tint mason jars and make them look like this, and all it takes is a little Modge Podge and food coloring. I found this easy tutorial put together by Heidi of My Beautiful Mess.
What I like about this tutorial is that Heidi paints the jars on the outside instead of the inside like most tutorials I've seen. This way, if you want to use them as floating candle votives or as flower vases you can. Personally, I think I'm going to use them to store odds and ends.
