I took me a long time to figure it out XD
I had tried ping pong balls cut in half, but they failed. Then, one day I was wandering through a dollar store and went "Hey, I could use those! If they don't work, I'm only out a dollar"
Best dollar I ever spent ^_^
That's a good way of seeing the loss of money. xD
I should try that sometime, I'm a bit too pessimistic.
Also, how can you see out the eyes of a fursuit if you have these kind of eyes?
They're like, glassy and covered with paint so you can't see anything.
