"Ambrosia maple" is, as I understand it, a form of spalting caused when insects burrow into the tree and introduce a fungus. It produces darker stains through the light-colored wood, roughly following the grain direction, ranging from a few isolated streaks to a chaos of overlapping "brush strokes". The holes are also present, of course, to add a bit more character.
It's often surprisingly inexpensive for a fancy wood, perhaps because the standard grading system considers it a flaw rather than a feature.
One of the local woodworking stores got a batch of this, and I picked out a few boards I liked for a project. (Blanket chest, so I'm leaning toward one or two splashes of pattern per side, possibly with a more chaotic/denser pattern on the lid.)
Question is, is there a recommended finishing technique that will best display the color and detail of the spalted patterns? Or should I just finish it as I would any maple project, going light on added color to let the contrast be seen? There's also the question of whether to fill the holes with colored epoxy or leave them.
Some of this, of course, will be a matter of taste. But if there are any known tricks or pitfalls...
