Yes or do molding.

You'll definitely want to continue with the tile. You will need to cut it, however. It's gonna be a little extra work, but it will look so so great when you're done!

Job do not look finish. Definitely you need add more tiles....

thanks everyone - yes I thought more tiles for that uneven wall - as it already has wood molding above. Has anyone used the metal trim profiles? not sure I can use the brand name on this site. I have wondered if we could use it around the window but not sure how to handle the corner - 90 degree. I thought this might eliminate the need to cut more tiles - this job has become very time consuming for my contractor and expensive for me.
