Have a 12" cherry vase I'm going to finish up tomorrow. My idea is to add flutes to the piece and then dye the flute cavities probably with a brush. I know I'll get a few spots at the top edge of the flute where the color will bleed over to the top surface or I'll spill a drop of dye off the brush etc. etc. Going to use the Artisan dyes from CSUSA that are alcohol based. Not sure how far these dyes penetrate but questions is: will these mistake areas sand out or will I need to take the surface down with a gouge?
