You may have seen mason jars repurposed as cute drinking glasses for a backyard party, or maybe used to hold flowers for a rustic centerpiece. But the folks at Jarware have taken things a step further, coming up with tons of innovative uses for the humble jar. Try out some of their fun, interchangeable lids to turn your jars into everything from a tea infuser, to a cocktail shaker, to a tea light holder. We love the super-creative salt and pepper shaker option, which turns one jar into a salt and pepper shaker combo with a special insert.
