I finally got the quilted maple veneer on the headstock and body to the point where I'm happy. It's sanded up to 2000 grit and has ~30 coats of Tru Oil. It's only at this point that I step back and notice that the veneer on the body has turned a not unattractive shade of yellow while the headstock veneer remains unchanged.
I'm perfectly happy with either shade. I'd just like them to match. Any suggestions?
