I didn't realize it was a faux stone pattern. There is nothing you can do to hide the grid pattern I am afraid...However, as it is recessed in a niche, I am inspired by your windchime pattern to think of adding eyelet hooks on the top and bottom that align with the vertical grids and uplight them from behind...This idea but with less vertical rods, and then uplit to give an effect like the second picture...

off white wall color will look sober with this tile color. But do you really need these wall tiles?? what is this space for??

The hall way is around 210 sq feet ,will black or dark colour make it look smaller?! Would you have sample pics (just in case )

Hello Ash, Jaipur Blue Pottery tiles are definitely suited for kitchen backsplashes and are heat resistant since they are fired in a kiln like other ceramics. I bought mine from a vendor in Jaipur, and got them shipped to Bangalore. Just make sure to be very very clear on what you want - hand-painted or screen-printed tiles; there is a big difference between the two. Happy to discuss further. Thanks, Gargi
