I decided to put this under "Try it Tuesday" instead of just "DIY & Crafts" because it's so stupidly simple that it barely counts as a craft. Really, the hardest part comes from washing the labels off the jars.
And, really, that's it: gather up a bunch of jars, soak them overnight in soapy water, scrub off the labels (using GooGone on the really tough adhesive). Clean, let dry, add photos. The only thing to keep in mind is the size of the photos: I found that vertical 3.5 x 5 photos work best. You can order them online from practically any place that develops pictures, and they're cheaper than 6 x 7s. Then, add a few tea candles, or maybe a ribbon around the rim, and you're set.
(As a minor sidenote: the front-and-center picture is of my sister-in-law getting pretend-mauled by the University of Cincinnati Bearcat. Very few college statues rival that of a big-ass carnivore about the devour something.)
