How do I copy a drawing from one project to another

Hey everyone! I am trying to move drawing layers from one project to another. I took someone’s suggestion to create a folder in the library and drag in all the layers. Unfortunately, that folder I created in the library in that particular project does not show up to the new project. Can someone as soon as possible please show me the trick to copy a drawing from one project to another? Thank you.
