This creative favor idea works past both issues, not only is it utterly adorable and affordable but your guests will probably still have it 10 years later. Now that’s a good favor.
Bubble Magnets. Have you ever seen them? They are very easy to make, cheap, and customizable. You can use pictures of the bride and groom, the hotel, beach, and date of the wedding, flowers or anything you can find that matches the color scheme of your wedding.
I have included a picture of some a bride made recently; they were a big hit among the guests. Also check out the link http://www.projectwedding.com/biography/list/sabbysara/diy-bubble-magnet-favors for detailed instruction on how to make them.
