Thanks for the tips! There are actually 41 canned designs http://www.makecupcakewrappers.com/Wrapper and users do share some of their custom designs which can then be edited by other users.

But, it's been on my to-do list for over a year to build a wizard on top of the custom designer with a step 1) choose a design, step 2) upload photo, step 3) enter text, type of experience.
