I love high quality tile work. I have A soft spot for the trowel trades.
However, These are boring ass construction grade 2x2 (cm? Inches?) tiles. Factory made, probably mat-set
Bro, have you heard of saltillo? Yohen? Grespania?
we talking 3/16” sanded groutlines? Kerdiboard? I prefer a 1/4” square notch for anything netted or >4”x4”
