I found the most adorable invitations for my daughter's birthday party at Michael's craft store. They have a lot of fun American Girl doll party supplies and crafts. I asked all of our guests for their dolls name so I could personalize the mini doll sized invitiatoins. For the thank you notes I used this template. It was supposed to be used for a version of pin the tail on the donkey. I shrunk it down and personalized it - then copied it and used it for our thank you notes.
