I scanned the pictures of the Disney princesses into my computer (from some stickers I bought) and printed four princesses. Also changed the 'heads' of the same four princesses to be those of my friend's daughter ! Altogether I put 8 princesses on the cake !
But.. I think the birthday girl was a bit shocked to see her own face on the princesses. She preferred the real princesses instead of those with her face ! But her mom liked it though !
Note : Children might not see the fun side of having their faces superimposed on characters or bodies that are not theirs !
