Cut a piece of butcher paper to the size you want your monoprint to be using a pair of scissors.
Locate a smooth, flat work surface in your home or work area. The surface doesn't have to be flat if you want to incorporate its texture into your monoprint. Use a Formica or marble kitchen counter, a linoleum-topped table, a sheet of Plexiglas on top of a table or even the surface of a large, plastic tray.
Apply water-based paints like tempera or finger paints to the work surface using brushes or your fingers. Vary the amount of paint you apply and the colors. Work quickly. Be creative!
Lay your piece of cut butcher paper on top of the paint you have applied to the work surface. Press the paper down firmly. Use the heel of your hand or the edge of a wooden ruler to press the paper flat. Work from the middle of the piece of paper outward to the edges.
Grasp one corner of the butcher paper and carefully peel the monoprint you have made from your work surface.
Clean your paints from the work surface using a soft rag and water and apply more paint if you want to make another monoprint.
