Opinions on fundraising idea!!( For neuroblastoma a rare cancer)?

Ok, so I am 14 and I love helping people. me and my cousin are just about completed with a HUGE service project in which we got 1000s of dollars worth of supplies for foster kids. I have been touched with stories of childhood cancer, and through my project with my cousin, I learned I can do anything. I want to raise awareness and money for neuroblastoma because it affects kids mostly very young and there is less than a half survival rate. My idea to raise money is to make hair bows and bow ties( from duct tape and strange materials) with my friends and church, and then sell them at public places and spread awarness as far as I can get it . Along with the hairbows I will be singing with my cousin(plays guitar) and collecting money :) I have the resources to do my plan, I just want your guys opinion on other things I can do and things I can change :) Thanks! <3
