Wedding guests are spending their time and money celebrating your wedding, so it is traditional to give them a token of appreciation.
They are there at your wedding to support and to rejoice with you on one of the happiest day of your life.
They make your big day fun and memorable.
A wedding favor is not simply a gift given to your guests.
It is a way of expressing your gratitude towards the special people who have come to witness your day of union.
Though a simple gesture, there is also an etiquette that must be followed.
Etiquette, by the way, is a code of behavior that coincides with social norms.
Here is the proper etiquette that must be observed when giving wedding favors:

• Prepare the right number of the items.
  Each guest should receive a wedding favor including the children.
  Or if you are on a tight budget, you can save by giving couples a single token for each pair.
  Provide extras just in case.
  There may be unexpected guests that may show up.
  Or if any favors break or get damaged, the extras can cover these losses.
  Then none of your guests needs to leave the reception with a wedding favor.
  
• Your favor should match the theme of your wedding.
  Everything should be matched, from the decorations down to your wedding favors.
  It is not appropriate to give your guests a decorated shell if you are having a Christmas themed wedding and vice versa.
  That will not be a pleasant set up, unless you're planning a practical joke.
  
• Attach a thank you note.
  The wedding favors are given as an expression of appreciation and gratefulness for sparing their time and support on their special day.
  So it is customary to attach a thank you note to the favor.
  
• Choose something that will last for a long time.
  Wedding favors serve as the couple's wedding souvenir so they must be something that the guests are willing to keep and add to the collection of wedding favors in their display cabinets.
  
• Place or arrange the wedding favors in such a way that your guests can easily access them.
  You can place the tokens on a each table where your guests can easily see them.
  Another option is to arrange them on a table and assign someone to distribute them individually before the guests leave.
