I found the beautiful toppers you see above at a great blog called A Little Lovely. If you have a party or celebration coming up, this is a really easy, really cute way to personalize cupcakes for any occasion.
This would be great if your child is like mine, and they pick birthday party themes that are not available at the party store. You could print a themed picture for the center of the topper instead of words.
Hop on over to A Little Lovely for a very simple step by step tutorial.
