Ongoing hunt for young adult fiction books from 80's/90's

introverted bookworm in the 90's, my grandfather would buy me whole boxes of books at a time from yard sales so I had a very wide range of books I read, I am trying to hunt some down I have memories of since all my books were thrown away without my permission when he died. 😕

will post one at a time with the hopes that someone can help. I apologize for the very vague description. tia

YA where a girl made homemade cosmetics and they had a fair at the school but someone broke in at night and destroyed all the booths and the town rallied and donated supplies so everyone could remake their booths. and it described all the cosmetics she made
