As your guests part, give them something that will not only thank them for attending the memorial, but something that will remind them of the person of honor.
For a parting favor, fill a cellophane dessert bag with the deceased's favorite candy, cookies or snacks. Tie the bag with a satin ribbon and tie in a charm with the deceased's picture inside. People can take these off the ribbon and string them onto a rosary, necklace or key chain.
As mentioned in the Food & Drink section, you can send guests home with their own mini cookbook that includes the deceased's favorite recipes.
