Depending on the color your going with on the exterior, if you keep it red or another darker toned color, I'd go lighter almost honey on the floors; knotty pine? I have always wanted to redo a barn into a modern/rustic home!

The home itself looks to be a contemporary modular with lots of contrasting wood panels. Your furnishings are a mix of contemporary, rustic, Asian, 80's and a big box store seating set.

Oh wow, it looks fantastic! The black looks so striking against the white, not too sharp at all. Congratulations on the house, you must be very excited to move in. :)

An entire wall of built-in cabinets and hooks and cubbies for your crafting stuff (and perhaps filing-type stuff and printer for the office). Take a good look at what you have and think about how best to organize and store it and what could be displayed to be pretty and what should be hidden behind curtains or doors. A fold down ironing board on a wall or back of a door somewhere would be great. A nice desk and filing cabinet for the office side... or perhaps a great big table in the middle under the window, wide enough to function for both of you facing each other? A nice curtain rod would make a big difference too. Preferably just about floor to ceiling. I'd put a splash of colour on the walls and keep the curtains simple, but you could go vice-versa too.
