Drew, check out my website www.sgranite.com and try to use the "granite color" in the current icon. It's called Santa Cecilia and the color currently really matches my website and would look an S to look the same. Maybe even putting an S into the Box and changing the font to your entry number 54. Thanks, David
Also enclose it like your entry 13 and fill in the space with that granite color. Change the S color to match my website. Keep the shadowing like you have on 13
