Download the blank, print 3 copies and off you go!

To clear up confusion on starting the chain:

To start it off you simply put your name at 3, when you mail it your name is moved to number 2 and your friend puts their name in 3. Once the letter has been sent to 3 people it will be a full list and stickers will stat being sent after that.

1st letter: #1___ #2____ #3 Lacey
2nd letter: #1___ #2 Lacey #3 Sue
3rd letter: #1 Lacey #2 Sally #3 Emily
4th letter: Jane sends to Lacey and changes letter, #1 Sue #2 Emily #3 Jane
