Space Mosaic WIP center panel grouted!

I grouted the largest piece yesterday. Black grout is the devil's own grout, but it sure looks good once you get it cleaned up. My fingernails will have to be clipped short although I did wear gloves and I coated underneath my nails with bar soap before I started . . . still the grout stained my hands! So the grout looks good but I am not going to post a pic until I get some metallic paint on it. That's what I'm doing today. So much fun.
