Personalized Present For An 18 Year Old?!?

I want to make something for my mate.I’m still 14 and she’s 18 this year but she’s like a big sister, she means the world to me.
She isn’t like loving as in she won’t tell you that she loves you but all her friends tell me that she adores me and is very protective of me. I’m very loving so i can’t give her hugs and stuff coz she’s not like that, but what can i make for her that she might like because she’s nearly 18 and i don’t know what some one of that age would like personally made.Parents and stuff never mind but coz she’s nearly 18 it’s different! Any ideas?
She’s very outgoing,loud,caring..etc
Thanks everyone!
