Girls, extroverts and feelings?

my crush is an extrovert and recently i have been giveing her notes cause im to shy to talk in person regardless she seemed to take to it positivly but suddenly she has been going with freinds everywhere that i would normally see her and makeing it hard for me to engage with her in any way while i realize notes are not the best long term i would appreciate knowing how to either one get her by herself and talk or any tips on how to engage her with a group of people i dont know who probably think i like her
