When my team does "sister bags", as we called them, we got gift bags and filled them with their favorite candy/foods/drinks and silly little things like silly bands, stuff from five below, and other random things. Every once in awhile some girls would do bigger sister bags and get their sisters a pillow pet, a board game (Cheerleading edition of Monopoly would be a good choice :) ), nail polishes, slippers, picture frames, and one time my big sister even made me one of those tie blankets (where you take the 2 peices of fabric,cut the sides and then tie them). I loved that blanket and I use it to this day!
