I especially like the image of a dandelion - something scattered to the wind, yet lives on with the promise of a wish. Seems appropriate when we've lost someone.
On another note, many of the items I feature are originally created for weddings. Although this may appear contradictory, I believe a remembrance service should be parallel to a wedding - an opportunity to gather together and honor the love we hold for one another. It's a promise to cherish someone forever, a bonding that transcends death. I wish that funeral services were half as creative as weddings!
