Paul, it is animal print tissue paper. Comes in giraffe, zebra, tiger, lepoard and a few other patterns that are too big for a bow backing. It is strictly decorative. The tissue paper is so thin it will tear easily as soon as it touches the wet glue.
I did a considerable amount of tempering on this bow. I heat straightened and heat bent the curves using a heat gun and oil but after she was almost tillered I did a good dry tempering. You can see the darkness on the belly. That is what remained after finish tillering and sanding.
