thats the only way to do that... is by making a live mold of the person, it a mold after mold proses, then making then scales and tail then make another mold ontop of that, but you would have only use Dragon Skin, as of now Dragon Skin is the only silicone that is skin safe (witch is not cheep stuff)... there will be no way if adjusting sizes, it will be only made for that person... so if you got into making tails for money you would have to make live casts for each client and its a hard hard hard proses...and long too... not mention expensive....so each tail would be vary $$$$$


oh and I wouldn't suggest just piling it on the live cast....it will just run and make a mess...you need to sculpt up scales and a full tail out of clay....
