I am not sure about soap idea? Lol but I like how the they wrapped these favors then out in vintage suitcase! Wedding Favors - Lavender Soap wrapped in kraft paper and twine, topped with a colorful sprig of lavender and displayed in a vintage suitcase.
CDs with lables that make them look like old vinyl records . You could also set up an old RECORD PLAYER and have REAL VINYL records for guests to play. Ooooh, perhaps even give the records as Wedding favors?
