are you hiring sally's hunks to do it? we liked that.
I love subway tiles. small and pretty colors! Yes, grey is a neutral color, but most folks who want nuetral go for a vanilla look with touches of other colors added or sprinkled in for effect. Think beige, vanilla, cream, sand. If you go with grey, you can chose lighter blues, greys, and even throw in tinges of things like lavender, or misty pinks.
Im so excited for you!
