2 Backsplash questions

[Andrea]

I am installing a travertine blacksplash in my kitchen. The tiles are 3x6 and I am using 1/8th grout joints. I also am putting a strip of 1x1 travertine and glass tiles in backsplash. I plan to fill in the natural holes in the travertine tile. I have 2 questions:

(1) Should I use sanded or unsanded grout?
(2) I've read a lot of different information about filling in the holes. Should I seal, install, and then grout the joints and fill in the holes? Or is there a better way to fill in the holes?

Thanks a lot for your insights!

The holes is one of the characteristics of travertine that makes travertine, well, travertine. Why fill the holes? If you don't like the look of the holes, maybe travertine really isn't "you".

just go with a honed & filled tile, this way you don't have to bother with the whole filling process yourself
