Love the idea of giving your guests seeds as wedding favors. Any seeds will work, but get personal with them. If your favorite drink is a mint julep & your partner's known for loving BLTs, then you could use mint and/or tomato seeds...be creative! It's a gift that will keep on giving & will be a great reminder of how much fun they had at your wedding! Seeds are super cheap, add a little package makeover by using some cute envelopes or unique paper from your local craft store, create a personalized message & you have just made a very affordable & unique favor your guests will never forget! This favor would pair perfectly with any vintage or rustic inspired event! Happy Planning!
