I understand that only the Scout wears the patches he earns [scout thru Eagle] on his left pocket, and when he becomes an adult Eagle Scout, he removes the Eagle Scout patch and sews on the Eagle Scout square knot. I didn't know this rule, but when I turned 18 I was told I couldn't wear it anymore, etc., so I bought the square knot that represented I was an Eagle Scout. However, I heard that [now] you can wear that Eagle Scout PATCH on your left pocket until you are 21 yrs of age. I dont know if that is true or not, can someone please help me out?
