In a white elephant exchange, guests can steal gifts that others have opened, so the best gifts are ones people actually want. Funny gifts get a laugh, but useful gifts get stolen. The sweet spot is something practical with a fun twist.
Stick to the group's spending limit; many exchanges set one around $20 to $30. Going far over the limit puts pressure on others, while going under looks like you did not try.
Gifts that appeal to almost anyone work best because you do not know who will end up with it. Think cozy blankets, fun kitchen gadgets, party games, snack boxes and desk toys. Avoid anything too personal, such as sizes, perfumes or inside jokes only you understand. Include a gift receipt just in case.
Wrap it well: a mystery shape makes the gift more fun to pick. For more ideas in the same price range, see gifts under $25, and grab some gift bags and boxes.
