Hi, Sam,
Beautiful work! Beauty is in the eye of the beholder so, if you like the
Red Mahogany, that should be fine.
My preference would probably be Gunstock or Cherry stain
so it isn't quite as dark as the Red Mahogany.
With other people's suggestions to use contrasting colors,
now that they are cut, you will probably have to wood-burn
areas to stop one color from bleeding into the other area.
I hope to see what your final decision is.
God Bless! Spirithorse
