What can I use to make grips for my felting needles? Apparently getting economic hand held felting needles in my area is hard. I can get single felting needles easy though. While I can purchase what I want online I would like to see what it would take to make my own rubber-like handles. I was looking to see how something like this could have been made:



I had thought about experimenting with hot glue or perhaps even epoxy. I thought of hot glue when I saw what looked to be bubbles in the casts above. Either way these ideas could lead to the ruin of my needles so I am hesitant. The colour is not important. 

What can I use to make the grips on felting needles that are like what is pictured above? Best I get from searching is something called Plasti-Dip but I don't think that will work here. I am aware that I can try and make a wooden style handle but I am trying to see how these are made.
Have you considered sugru?

A silicone-based rubber for lots of "hacks", adding ergonomic grips or softening handles being one of them.

The material can be removed from all non-porous surfaces, so your single needles won't be harmed.
