The slogan "Decorate your own desserts" should be fairly easy to remove in the future in case we decide to make the logo more subtle, like Starbucks did.
We attached cupcakes.jpg mostly to show some colors that help convey the fun feeling at Whimsy [colors don't have to be exact--this is just for inspiration].
Logos.docx shows examples of some logos that we like.
Obviously our target will have more women, but we want to keep the logo fun and whimsical without being too overly feminine or overly infantile. Disney does a good job of emphasizing the magical experience for all ages without being too girly.
If it helps, here are some descriptive words we wanted to encapsulate when we were trying to decide on a company name: Whimsical, fun, creative, sweet, family-friendly, making memories, decorate, do-it-yourself.
