Moulding on the wall is a great way to create interest on the wall like this. Also consider a gallery wall. I think the polka dots would work best in a children's space, but of course your house is your castle! Do what you love.

hmmm.. gorgeous tiles, but would have to agree with the others, may be distracting, and they seem somewhat reflective as well. Also, may be a pain to dust.. and if your TV is in the same room as the kitchen (open plan) may find that grease settles on them over time making them even more painful to clean. Lots of other beautiful and practical options on the market though. Maybe if you post a photo of the room, may be able to provide more targeted advice. Cheers K

Just a suggestion but have you thought about a deeper grout to showcase each tile a slightly deeper grey to the tile will showcase the patterns so they don’t get lost into one another.. Plus so much easier to clean! If you’re afraid to go too dark then go two shades darker than the tile.. Either way will work.. but as a professional having used similar tiles I always like to showcase with a deeper grout.. Just a thought!!

I would say light grout to highlight the feature tile and tie in with the tiles next to it, as dark will make the penny rounds recede a bit. Alternatively, dark grout would give a more moody feel - if this is what you are going for?
