Didier FAUGUET estimates that it takes one month to make a cross..
Of the crosses studied, some seem to have been carved with a concern for symmetry, others were made in a cruder manner. Some crosses were made with great skill and are the work of masters of their art, others are more crudely made. They seem to have been made by "apprentices".
Since time immemorial in our region, many people had the basics of stone-cutting, if only to make a more or less straight face on the stone walls of their homes.
Most of those who made these crosses did not work with geometric notions, but « bye eye » hence the slight asymmetry of the crosses.
