How do you write your name in flag semaphore?

How it works

Flag semaphore sends letters at a distance with two flags. The signaller holds one flag in each hand and stretches each arm in one of eight directions, 45 degrees apart: up, down, out sideways and the diagonals in between, and across the body. Each letter is one pair of positions.

The signs here follow the table of the Australian National Botanic Gardens, written as left and right arm positions. In the drawing, an arm's angle is counted from straight up, turning away from the body: out is 90 degrees, down 180, and the positions across the body 225 and 315. For example, A is the right arm 135 degrees (low) with the left arm down.

Digits reuse the signs of A to I and K after the Numbers sign, and the sign of J tells the receiver that letters follow. Semaphore has no punctuation here, and the rest position for a space is not part of that table: it shows both arms hanging down. Real signals also need agreed ways to start, correct and end a message.
