My favorite ideas from the site include...
-wrapping a present in old sheet music (perhaps a Christmas carol?)
-using last year's holiday cards as gift to/from tags
-using old jewelry as a tree ornament
-baking and creating an edible holiday greeting card
-giving all the makings for a starter garden: seeds, gloves, hand tools, etc.
-giving a reusable, BPA- and plastic-free travel coffee mug
-giving a personalized coupon suggesting a favorite activity that you and the giftee can do together
-donating to the local food bank
Regardless of what you give, always ask yourself: how am I impacting the world with this gift? could I have bought it for the same price from a local seller? could I have made it myself? will the person I'm giving this to like it, or will he/she just throw it away?
Ultimately, it's your money, and your decision, but the holidays are a great time to give a little more thought into our actions.
