I can't begin to express the amount of inspiration I found at Universal Studios, Wizarding World of Harry Potter (not-sponsored). Simple details can give you the biggest ideas. Feathers! Why not use feathers in your centerpieces or even more exciting, why not have a real ink well with a quill for guests to sign an antique looking love spell book. You could even include prompts for guests to get extra creative in your special guest book.
