Beautiful piece! I like working with B. Elder. Sure does make a nice piece. I have a wall hanging from a trade at another site i used to frequent made of Box Elder. It is my favorite piece.
That's easy--------Keep it out of the sun light.
If you think about it all wood will fade out if left in the sun. Yes box Elder will do it faster than other woods but they all will do the same thing.
Even at a show I keep them in a dark place.
