Hello Shannon,

For this fireplace I used glass mosaic tiles that I purchased from Ann Sacks, but many other retailers also carry this brand. They are made by Oceanside Glasstile.

I have attached the page link and a photo of the 1" x 1" tile blend that I used, Viel. The accent black/stripe pattern I added by buying a sheet of glossy black tile.

I hope that this is of help : )

Thank you,

- Angela
