Answer 1

Take some aesthetic patterns from internet and print them and cover this print or cut the shapes as you want and stick it on your book.

Use glitters, stickers to make it jazzy.

Draw some basic patterns like polka dots and colour them for a simple yet elegant touch

Simply bind it with a cover you like, readily available from stationery store and you're good to go!
