I am also a really big black pastel fan (love that leisen line), so I wanted to work on them also. That's really why I am asking this. I don't want to run headlong into deformity issues, and be seriously saddened by babies coming out with difficulties. That would not be good for the animals or me!
It's just weird that there isn't more info out there about it. I guess we don't have any more info here on BP.net though :/
