What I am referring to here were cases of other art being copied - not other cookiers' designs. The original artist was easily identified and located, because the pieces were that unique.
All I am asking is that if you know that you copied something from someone, and you know that person's name, then please credit them. It only reflects poorly on you when you don't and your omission is brought into public view.
And, yes, all copies of licensed character cookies on this site must go in the "Characters" clip set and should be tagged as "Disney" or whatever character they are. However, to be clear, I don't support the copying and selling of licensed characters (it's a copyright infringement if you don't own a license/have permission, and Etsy sites have been closed down because of this). I have this clip set because, as one person, I cannot control the flow of licensed characters on the site. But if one day I am asked to remove them all by Disney, it will be an easy thing to do!
