I want to be able to trace images onto cookies, eventually. Right now I am a beginner, but I have big dreams. I just can't see spending the high amount of money that cookie projectors cost. I have read about how to make your own, but then last night I was looking at social media, and an ad came up for a device called an "optical image drawing board". Apparently you use it to project any image from your tablet or phone to a surface onto which you can trace the image. I have looked at several and they are so low priced that if they work well, I am going to get one. One problem I can see is possible sizing issues, but I suppose the image could be copied into a program where it could be sized. Has anyone used one of these optical drawing boards and, if so, what was your experience?
