Trash becoming treasure is the unending circle of DIY. The treasure, in this case, is a hand-crafted ornament that rivals any of the equally sparkly (but certainly pricier) options in holiday aisles. It's just made from basic ball ornaments and the broken pieces of discarded CDs.
Natalie of Crème de la Craft found that cutting CDs into small pieces with a pair of basic scissors creates something that looks like jagged metallic mosaic tile. And when those pieces of "tile" are hot-glued shiny-side-out to a basic Christmas ball, the result is a perfectly festive disco ball Christmas ornament.
Watch the video below to see how it's made, or check out the full DIY instructions on Crème de la Craft.
The plain ornaments can be found in inexpensive packs from craft stores or discount stores (I found this set on Amazon that's $6 for 4 ornaments). Then gather up some CDs (about 1½ per ball) by clearing out formerly-blank CD-Rs from your desk, purging an old album collection that's been digitized, or collecting used AOL internet discs from somebody who's been hoarding them since 1996 (but really...if you're still hanging on to these, it's time to let go.)
A whole bunch of these ornaments can be crafted for just around $2 each. At that cost, fill the whole tree and make those Christmas lights really sparkle!
