How to use it
Type up to 60 characters. Each letter becomes its flag, and each word gets its own row. Accented letters lose their accent, so Zoë becomes Z, O, E. Numbers and other characters are skipped and listed, because we only draw the 26 letter flags.
Press Print an A4 sheet for a page with the name, the flags and each flag's name under it. Set the printer to actual size. The line at the bottom should measure 50 mm with a ruler; if it does, the sheet printed true.
How the flags are drawn
These are the letter flags of the International Code of Signals. Each one has a set pattern, written down in heraldic words called a blazon. Delta, for example, is "or, a Spanish fess azure": yellow, with a wide blue band across the middle.
We drew all 26 ourselves from those blazons and checked each by eye against the flag pictures in the source. The colours are plain red, blue, yellow, black and white. Alfa and Bravo are swallowtails, cut with a notch at the fly end.
What a single flag says
Flown on its own, most letter flags carry a message. Alfa means "I have a diver down; keep well clear at slow speed". Oscar means "Man overboard". Romeo is the odd one out, with no single-flag meaning today. A name spelled in flags is for show, not a signal.
