I need help with designing a book cover for my teacher (details to follow~)?

I think you should do something related to the class. did your class have any inside jokes? if so you cant draw a picture representing it or write a quote about it and put it in the center of your cover. then surrounding it you could put fun little designs like swirls and hearts and so on. i know it may sound a little feminine for a gym teacher but i gave my gym teacher a little book once that had inspirational quotes and hearts and she started crying and hugging me!
