Here's a great little idea.
Kelly Wilkinson, from the craft blog Make Grow Gather, posted this simple "upcycling" project that seems like the perfect Saturday afternoon activity.
Kelly's helpful step-by-step guide on flickr (link broken - see comments for updated links) shows how she dismantled a bunch of old jewel cases and glued them together into a cube.
She printed her images on vellum paper (or tracing paper) so that the candle would produce a soft glow.
Then, using the CD label as a template, she cut her images to fit and inserted them on all sides.
Lastly she finished the whole thing off with a bit of ribbon to hide the edges of the CD cases.
