555 - How to make a LED flash twice every second?

I know that I can make a LED flash using a 555 timer. How may I make it flash twice every second?

What I am trying to do is to make the LED flashes two times, then wait a second, and then flashes two times again. In pesudo code is something like this:

while (1) {
    LED_BLINK_ONCE();
    wait(10ms);
    LED_BLINK_ONCE();
    wait(1000ms);

}
