Find and meet pilgrims from the forum while on the camino with the forum badge. This badge is 7 cm in diameter (it fits just inside the palm of your hand) and can be sewed on to your backpack or jacket.
Why a forum badge?
You do not need a badge to be a pilgrim. The idea behind this badge is for you to get in touch with other fellow forum members while on your camino. Also, "everyone" in Spain will know that you are a pilgrim when they see this badge. Your backpack might also tip them off :-) but the yellow arrow is a known pilgrim symbol.
