Hello everybody, I recently found a tutorial on how to make your own Kopykake. The idea is roughly the same, to project an image onto your cookie and trace over it with icing. I am working on making one myself, since I don't have the funds for a real Kopykake. Based on the tutorial, it seems to work very well. The only difference is you won't be able to change the size of the projected image as easily as with a real Kopykake. But for the difference in price, it's fine with me. Below is the link that shows you how to make the projector.
The link below, shows how to use the DIY projector.
I hope everyone has a wonderful day, Rebeca
