Personally, I have five knots on my uniform. In the order that I earned them: Youth Religious (earned twice, once as a cub and once as a Venturer), Arrow of Light, Eagle (I wear my 3 silver palms and yes that does translate to nine palms total), Venturing Silver Award, and the Venturing Leadership Award. If I would have to choose a single favorite, I would choose my Venturing Silver Award. This is really the only award that I ever really had to work for as a youth.
When I went through Commissioner Basic Training this past year, they made a good point about the wearing of knots. They first asked if anybody was in the military and then asked if they wore all of their ribbons on their uniforms. They said that we as scouters should wear all of our knots with pride. We earned them so we should wear them.
