A method of making graphene sheets having a desired thickness. The method starts with Highly Oriented Pyrolytic Graphite (“HOPG”). A plurality of graphene layers are pulled off of the HOPG and attached to a substrate. An adhesive device is then used to pull a selected number of graphene layers off of the HOPG sample attached to the substrate. The number of layers selected determines the thickness of the graphene sheet produced. The graphene sheet has many applications. It is particularly suitable as an X-ray window.
