Thank you for the reminder. I try to make my own designs but recently I was asked to do a "working interview" for a cookie decorator position at a local bakery. They gave me a picture they found on pinterest to copy. They really turned out well, and I posted them. However, I did not get the job!
But, this experience inspired me to just start selling cookies on my own and it's going very well. The cookies I had to copy were Peppa Pig. When doing character cookies like those, you don't really have much choice if the client wants them exactly as they are shown.
