Zig zags were made famous by Missoni. Now you will find them everywhere. Pillows, mirrors, even furniture.
I absolutely loved when Mary McDonald from Million Dollar Decorators redesigned an office for one of her clients turning it into a statement… complete with horizontal stripe curtains and a bold zig-zag patterned floor.
It can be quite expensive and if your afraid to take that risk off painting the floor try to find a large area rug you could use in place of paint. I recently found area rugs at West Elm which could cover the majority of the floor.
