I never knew they did that.
I haven’t tried,but it’s a good question. I know on another forum that I was on someone was talking about a doll that someone had tried to do that but it didn’t work. I think they were trying it on toes, though. I would think you could IF you could tell that there was enough vinyl between the fingers. I have a test hand of the 9 month toddlers. Maybe I’ll get out the exacto knife and play!
When I get a chance, I will. I won’t be at any loss with a test limb. Who knows, it might work.
