Graphene is made in various ways, ranging from scotch tape (relatively large crystals), to ultrasonic dispersion of graphite in water and soap (tiny microscopic flakes) to vapor deposition for large films, and all sorts of other variations of those themes depending on what you want. Flakes are trivially produced and are starting to be used as additives for desirable structural, electrical, and chemical effects.
Graphene was initially created using scotch tape, however, and it remains a reliable and simple method of getting high quality graphene for lab experiments.
