It's a split foyer so we can't take down the wall and open it up into the living room. It's pretty small so I want to try and maximize my space and storage. (excuse the mess) I want to create a feeling that is warm and relaxing. I love and are drawn to: the modern farmhouse design, craftsman style and cottage design. Any ideas would be greatly appreciated!

Here are my dilemmas.

1. The size and shape of the kitchen. My thoughts were to extend the counter top the whole way around along with cabinets.
2. What color do I paint the walls? I hate the yellow paint! The kitchen, living room and foyer are all the same color. What do I do about paint?
3. Window treatments: We have a sliding door and window that are all different sizes and a window next to the sliding door (not sure why). Do I do long curtains for the window along the wall and short or valance curtains for the other two?
4. The couch: It's a crimson color couch with khaki pattern. Pillows? Paint color for the walls? Curtains? Artwork? I don't know how to match anything to this couch!
5. The chairs the kitchen can be reupholster but again what type of fabric/patterns do I choose to match with the couch and window treatment? I thought about building seating along the wall to give more space and get rid of some of the chairs, or maybe a round table instead. I did need enough sets for at least 6 people.
6. Foyer wall: Art? Family images?

Thanks for taking the time to help me!
