I wish I had documented that. I will look back at some old photos and see if I can find it. I filmed this before I knew much of anything about filming, adding documentation, or RU-vid. I just wanted to share it with my students.
It's a silicone clay sculpting type tool. I found them on Amazon in a group of tips that had different sizes. I don't know the brand, and I'm not home to check. They didn't cost much.
