Custom Bandz created Doll-n-Me Do-It-Yourself silly bandz kits! You can print them out from http://www.custom-bandz.com/order.php. The main print out is only $6.99 and the Doll-n-Me add-on pattern pack is just $0.99.
My daughter has figured out that the mini silly bands you can buy also fit her dolls perfectly. I need to take a picture of Chrissa, Sonali and Gwen having their silly band trading party.
