Origami has been one of my hobbies since I was 8 years old. Almost all origami pieces start with one of the origami bases: a folded form that starts a piece. This is one such base. You can find a list of all the bases I have tutorials for here: https://jessieathome.com/origami-bases/
Start the Origami Book Base with your square paper with flat sides on top and bottom.

Fold left side over to right side and crease.
