Take it to the end of the counter top.

Almost finished! Now trying to pick the grout line color. Looking at bright white, snow white or antique white. Any suggestions?

It looks great! If you want the tile to blend with the cabinets and countertop, use a white grout that matches the tile. It's difficult to say which white matches your tile without looking at it in person.

Or you could use a light gray which would outline the tiles and feature the pattern.

Light gray with your countertops would be pretty ...

Flo, I totally agree. I wanted it clean and simple, and then add color/texture with accessories. I had many years with color, and I was ready for a neutral setting.
