Maybe waiting is a good idea. There are many on GW who
have waited years before putting up a backsplash. Don't
rush your choice, let it come after thinking and dreaming.

What do you like?
What is your style?
What is your favorite shape? Color?
Your kitchen gives off a clean lined feel and the
beautiful suggestion by Sue-B could be fantastic. Do you
like that? Are you looking for subtle texture or maybe
soft matte or shiny?

One way to figure out your loves is to start clipping your
favorites. Use the green leaves and scissors up in the
right corner of the posts. And start clipping your
ideas together. After a few weeks start weeding your ideas.
Figure out which ones are in your top 10.

Meanwhile here are a few ideas. These are not to confuse
you but to generate some love or dislike so you can narrow
down something you find will work perfectly for you in
your kitchen.
