The common definition for medallion (or medal) is:
a circular object stamped with an insignia.
A medallion (or medal) is an object often used by organizations granting an award or recognition for a certain achievement.
It seems appropriate to design a logo that represents this idea, in a eye-catching form: a medallion hanging from a ribbon (or a simple medal), stamped with a stitched line hand, looking like an object (hand)made out of paper.
