What would it look like if you put the black and white strips on a solid or solid looking background - like red, or teal, or lime - some fairly intense color ? Then bind it in black.
If you use the gray, I would not add any other color to it. Just bind it with black. It's sort of intriguing with the gray background - but it sort of looks like the strips are on a design wall and not 'for keeps' on the light gray.
