I am searching for an idea for a 8 year olds birthday pajama party. The girls will not be sleerping over. They will just come dressed in their pajamas and go home later on that night.
There is a baby shower cake here on this site, the person made a onsie out of fondant it is beautiful. Maybe you can do the same only this time make a template of a shirt and pants. Maybe something simple pink pajamas with white poka dots ( did I say that right? poka?) anyway. Hey you could even try doing the buttercream frozen transfer that way you can get more detailed on the pajamas
(I am all for the frozen transfer, I am working on my son's guitar frozen transfer ( ice cream cake) Wish me luck!! Hope this helps! Don't forget to post your cake when your done, I would love to see what you come up with.
you could model the "power puff girls" out of fondant. Have the 3 girls each with a pillow on a bed (the cake) having a pillow fight. I think Debbie Brown may have this one in her cartoon charater's book.
