I did my research before choosing these vinyl subway tiles and by watching some DIY videos.   I'm an amateur at home improvement projects and this one had its challenges but the end result was so worth it.   The cost savings alone is significant.  The tiles are easy to cut  (I used a scissor and my husband preferred using an exacto knife) and they adhere beautifully, just be sure that the wall surface is clean and free of any grease.  I will also suggest ordering a few extra  in case of measuring or cutting mistakes like I experienced!  My backsplash project is a huge success  and I recommend  these  Art3d peel and stick vinyl tile sheets.
