I have a cake tomorrow that has to have these incorporated into it
its for a 50th birthday and she loves her 3 dogs, is a wonderful mother of 2 kids, a teacher, artist and loves god. Any ideas?
Thank you!

How large of a cake? Tiered or sheet or round?

8 and 12 inch round cakes

How about "snapshots" around the sides, like a film strip or a photo album or even post cards, with all the important things in her life depicted? You could print all the photos as edible images, too.

I do lots of these combination-interest cakes. I call them "Life Quilts". Each section has a different interest or milestone. Mine are all done as simple sketches in buttercream on sheetcakes, but it would work very well on the sides of a tiered cake.
