I helped a friend with her daughters Sweet 16. One of the things we had for the kids to do was each make a special page for Lizzy in a scrapbook. Scrapbook was set up on a table with chair and all of the supplies. Each friend was told beforehand to bring a pic of themselves with Lizzy from any age.
Was over a hundred dollars to do this due to the Embellishments purchased for the kids to use.
