Been having fun with 4” travertine tiles found at our local ReStore for 20 cents each. Fun for us good for Habitat. Also found some edge pieces of tile tried a file I didn’t realize had some little artifacts in the white portions but as a test it looks cool.
Masked the travertine with blue tape, then used alcohol ink to color. Used a sharpie on the tile with the mountain.
The black tile I put the alcohol ink on then lasered.
