While Tucker may never be a lion (and we don't need to let him know lions are cats, after all), at least part of his dream could be fulfilled. He could dominate his pack of friends with the most glorious mane of them all.
And this is how Tucker got his mane.
Step 1: Get measurements
From these, I was able to construct a mock Tucker head out of paper and tape.
Step 2: Making the base
I draped a soft lycra piece around the head and collar to use as the foundation for the fur. The collar piece closed on the side with strips of velcro.
Then I was able to play around with the fur until I could get it to look like what I wanted.
