Yup - no paint.
I'm lucky in that most of the Walnut I buy is from a local sawmill and it's unsteamed, far prettier than steamed Walnut. I've never stained any of that, fwiw - too pretty like it is.I can't either. It is beautiful the way it is. I use walnut stain on walnut these days too. The walnut we are getting is steamed walnut and unless you can find Caro walnut it has a sort of "Purplish" color with clear finish. The walnut stain turns it into a dark chocolate color which enhances the walnut in my opinion. Great job on the bear, just love the color.

I found the STL files on Ebay or Etsy.Wow looks great. Did you do the design. I have seen some other animals with the same kind of background and wondered who did them.
