A little unconventional here, but we have a mixed bag of glass tiles, mostly 4x4, in a few different shades of grey, blue & green. Looking at them all together, they have a kind of spa like vibe, tho I could also see them working well as a random pattern accent in an ultra modern bathroom or kitchen. Counts of each are as follows: Light Blue - 84 Tiles Silver - 64 Tiles Grey - 65 Tiles Dark Green - 48 Tiles Light Green - 9 Tiles Pearl - 35 Tiles Brown & Blue 2x12 - 32 Tiles I estimate at least 30 SF of coverage in total.
