Feathering or feather crotch figure mostly encountered in the butt stock portion of a high end stock blank is different than fiddle back grain structure, which is what you have pictured. Not trying to be a stickler for detail here but your stock is a very nice example of fiddle back from the fore end tip right through to the heel of the stock. And yes you could get away with a dark stain which should then be rubbed down to expose the end versus the side grain of each individual wave of the fiddle back, one absorbing the stain and one resisting it. Looking forward to seeing the finished product. Regards, David.
