For preparation, let's think about two C's cleaning and choosing cleaning. If you get your workforce across supply store or a departmental store, wiping it with dry cloth will do. I wouldn't necessarily introduce water. Because there are times when it leaves watermarks on the word especially the word is not treated, so you want to play it safe. When it comes in all shades of brown, that was a lovely contrast white and metallics, while light colored whips can help your black ink stand out more. Think about what ink or paint you're using to decide on which shade of brown you want to get a note on the type of word before buying your pieces, especially if you're working with a country that would like so ask what kind of what is it so this is driftwood, but you might want to see if you know what kind of wood is softwood, if it's soft wood like pine it will absorb a lot of ink and will cause feathering when you're doing your piece.
This may be the effect that you're going for but if not, then that's something to consider. If you prefer to get crisp lines then use wood like birch or walnut or use wood that's already been treated.
