Have you seen the gorgeous large triangle, overall floor patterns on the blogs? I personally think they are totally gorgeous. I don't have any of my own photographs to share but I bet of you do a search for painted flooring and I bet some of them will turn up.
Another thought: I've seen large squared plywood floors (in Amish homes in particular) and when they are varnished, they are very attractive. Perhaps you could use stain as paint, and stain every other plywood square. For example one square a translucent grey stain, the next square a darker stain (or whatever color you select) for a light and dark pattern overall. Be sure to post your final design!
I am looking for the project to make gazing balls for my garden. Someone used some kind of caulk. What was it?
Stencils can help with painting a wood floor. You can get large ones on line or at Hobby Lobby. You can also make your own design with a ruler/yard stick and painter's tape.
thanks a lot guys i appreciate it.
Assuming that your floors are pine, varnish them with a color of choice. Let dry and cover it with 2 to 3 coats of clear polyurethane. If you want to cover the floors with a color,choose the color and design, if any, and finish with the clear polyurethane.
