all my eyes are custom made here in my studio - and 99% of the fur we purchase is off the shelf fur that needs to be distressed. And you are correct I am sure there are posts on here that can go into detail about these topics - have a search then experiment with different materials.
Hey Sam, if you can't find the info on fur you're searching for here I'm 99% certain you'll find something on it over at Puppets and Stuff; a vibrant and active community of puppet makers/performers. If you're not on there already you owe it to yourself to check it out!
Jarrod, I've always been a huge fan of your work. I recently saw your scaled down fully poseable Miss Piggy. Can you give us an idea how you did this and what you used for the armature wire skeleton and how you place that inside the puppet?
