After a first course given in French and English (with an Italian translator to complete the picture) in MiroModo, Italy this winter and, in anticipation of other courses of the same type, I decided to compose small panels to identify the preferred language of the trainees I am addressing.
As I only speak French and English, it’s not too difficult to do, here are the first copies.

the reproductions (no, I didn’t compose each copy manually) are less good but still usable, so that you can better distinguish the patterns, here is a better quality version of each side.
