We have a soft spot for puzzle pieces when it comes to design. It's one thing to use them on our tables or in our gardens, but Puzzle Floor really hits it out of the park with their puzzle-piece hardwood floors. Each piece is made from northern hardwood and is available in 13 different colors that will flatter almost all rooms. The colors can be mixed and matched to create unique designes, if desired. There are two shapes, a "male" and a "female" which snap together easily, much in the same way that laminate flooring does, though the sealed hardwood will last longer than laminate because it can be refinished every few years to eliminate any signs of wear. The flooring is $15 per square foot.
