Roger,
I sent a swatch of this leather, it's 2 tone but I should only need the secondary color. A dog used it a lot and the color is almost completely worn off the bottom cushions, there is also some color loss on the inside back. There are a few light scratches on the inside back too. I'm ordering 1 quart because she has a few other pieces that will need to be worked on in the future.

Can micro pigment be used on waxed aniline?

Original swatch laid over bottom cushion. Looks like grain has been flattened out too.
