I love the Marmoleum natural linoleum flooring. It comes in tiles and planks, and the Marmoleum Click series is a great floating floor that is perfect for DIYers. Old campers usually have some sort of linoleum flooring (probably asbestos, too), so using the new, green Marmoleum linoleum seems like a good nod to the past. Today I worked up some really rough mock-ups of some Marmoleum planks/tiles on the floor of The COMET. I was working in stripes, and will probably try some sort of zig-zig or checkerboard variation at some point too. I also have that dark hardwood flooring I found for free that I am trying to incorporate in some way, but I only have 20 sq. ft. of that and the entire floor is 50 sq. ft. I am thinking about maybe using the hardwood up front and the Marmoleum in the kitchen and the back, but we'll see! Anyway, I thought I'd share! Let me know which combination is your favorite in the comments! There are tons more colors available, these are just the ones that stood out to me.
In the showroom at G Green Design Center in Mashpee, the Lime color was my favorite (the model directly above this text). But in the models, I really like the light blue color with the white (which is actually called "Barbados"....fancy!).
What may end up happening is I'll find a remnant and won't be picky about color at all!
