How do I line alligator's flesh side with.....?

[AWORKOFMARC]

Came across some alligator...seems a tad thin and I need to conceal the flesh side on the inside of the wallet I want to make... With what might work best? Duck canvas or a thin piece of leather?

My first thought is to line it with a thin piece of leather, like pig skin , goat,  kangaroo etc. I use roo leather for wallets myself .
