I have a friend who is a scrimshander by trade. It's how he make his living. In total; He's an artist.
He says most people over-look the obvious. "What is a cow horn? A: Compressed Hair!"; therefore when he isn't doing historically correct or repairs on originals, he uses....HAIR DYE! Sounds crazy, but I've watch him with some of his pieces, but it works. He did a red F&I Indian Horn, for a savage reenactor,that was exquisite. He used ladies red hair dye from Revlon. get some from a wife or female friend and try it on a scrape piece. :m2c:
