Had I known about this earlier in the summer, it would not have been a problem. Even with a new piece of wood. Buy wood, take to desert, toss in out of the way location, come back in a week, flip boards over, come back following week and collect..
The grey wood on the Douglas Fir page is similar to desert aged wood.
No, I have no experience in aging wood, but I bet it's not that hard.
If guys can relic a new Les Paul to look old and make it look authentic and sometimes fool experts, it can't be hard to weather a piece of wood.
In fact, I know I could.
