Whether done with a rug, paint, or the flooring material itself; striped floors bring high impact visuals to the kitchen:
When done on hardwood floors, the stripes can follow the planks of wood. It's a great idea for a coverup over floors that are less than perfect. Rugs are an easier, quicker and reversible way to add stripes. And stripes that are integral to the flooring material (as in the linoleum used in the Design*Sponge floor) are the most permanent of all for the bravest of stripe-lovers out there.
