How we do it is we collect all the walnuts after they've fallen and turned brown then place them in the driveway - and run them over MANY TIMES with the truck. Let them sit to get the hulls (the big green/brown outside part - thats where your stain comes from btw) and then using gloves (KEY PART THERE) we take the dried nuts and throw them into a wheel barrel and put them into the garage and let them dry even more.
They will stay that way for a long time.
you can make stain out of the shells along with the outer casing - just make sure you wear gloves handling the walnuts too because you will still get stained fingers
