pique assiette - yes that is exactly what it is.  The grout color is beige throughout. I blogged a How To. Check it out.

Sweet! Looks like pique assiette (that's just a french phrase for mosaics made from "cast-off" broken dishes/crockery)? What grout color? Looks like maybe black on the top and white on the black part?

Thank you for being my mo-buddy in a sea of paint!
