Je m’appelle (put your name). J’ai (put your age ie. 16) ans. J’ai les yeux bruns et les cheveux bruns. (or put the actual colour of your eyes/hair) J’écoute beaucoup de musique.
Some other ideas for you:
Put how many siblings you have, what you like to do in your free time, your favourite show or movie. Describe what you’re like (ie. funny, kind etc)
