Don--when you mold a fish you copy a fish when you mold a skin mounted fish the body was sculpted by someone--no? If it wasn't sculpted by the mold maker I would think permission would need to be given to duplicate that "form". Is it ethical to copy someones sculpture even in part. In my eyes it isn't ethical --you should carve your own body for this process. Is it illegal--I don't know and don't care since it isn't a body I produce. Your also an "expert" and thought the interested parties should know that there may be a cause for concern about marketing such a product. Illegal it may not be but it isn't very ethical in my opinion. Carve your own mannikins and don't copy someone elses sculpture. Not sure what" leave it to me means' but I will add this--good post besides the above mentioned. Jeremy in your descriptive some of the terms and products are a bit misplaced--Both Don and I (Hope I can speak Here for Don) use a bit different products. We both get good results using our specific materials and they can be interchanged. I would suggest, since this is your first attempt that you utilize just one of our methods so as not to be too confused. I have a pretty self explanatory article in breakthrough and you can always call with questions. Don has a website with contact info and I am sure He will be by bye here sooner or later. Good Luck with your sons fish!
