Rentaltux and Bill, thanks to both of you for your ideas! They are both great but I will go with the 9-12-9 inch design as it is closest to the look I am going for. Thanks again!!! I am so relieved to get this figured out!

No fire place...oddly enough the fireplace is in the ground level/basement. The TV will be opposite the couch on the right smaller wall. Only picture I have right now as I am not phone.

Photo for inspiration as you have not given measurements for each area: Position the back of a loveseat with back facing kitchen area. Possibly you could put a sofa table behind. Entering, the area will look spacious and welcoming.

Thank you! I think I have those exact 2 saved off as examples! My porcelain tiles are manufactured by Daltile. On their website they provide layout pattern templates in pdf. Herringbone and straight herringbone were both both suggested for 12x24 tiles. So I guess it really does vary by manufacturer! I'm definitely going to use on of these patterns
