This customer did Flow Ice 12x24 and went vertical. Most people do horizontal installations and there is no right or wrong way. The FLOW series is popular in all colors. ICE and NATURAL look very similar. Even IVORY is only a hint of brown in the color. Nevertheless, the mosaic, also purchased at KY TILE CLOSEOUTS , looks great with the Flow Ice. The multiple colors in the mosaic compliment the lines in the tile. Neither the tile nor the mosaic look busy together. Ice is a primary grey color with hints of white. The light brown in the mosaic looks brown/grey and just pops "enough". And the brown also compliments the wood-look floor. Yet, the most important part of this job is the customer reaction - "love, love, love the way it came out".
