As per my previous communication with people on this board, I am in the process of equipping my love doll with a suitable rapunzel wig. So I do not just do jerking on wigs, but I have a fully equipped doll.
There are lots of issues to solve, such as degradation of the fiber in salt water (I take her out on my boat). And recovery after daily wear and tear.
I have been given some good contacts here. But I am collecting things for experimenting . One thing that comes to mind is lotus silk, which apparently is one of the best materials more soft and pleasant than silk. But very lightweight.
I will have to see how every material works out. We will see.
