I have 13 and I wear all of them on one shirt. These knots signify my journey as a young scout and then through the years as a scouter. My top three are Eagle, Silver Beaver, and the NESA Scoutmester Award of Merit. As a side note, if we took a picture of my nuclear family of 5 there would be 2-four beaders; 1-three bearer, 2-two beaders; 3-Eagle Scouts; 2-Silver Beavers;2-District Awards of Merit; 1-Sea Badger; 3-Explorer Post Presidents; and a Vigil Honor OA member. We also have one almost Eagle Scout. I'm pretty proud of this Scouting Legacy. P.S. : On all of my other shirts I wear 6 knots.
