Print or draw a butterfly on a piece of paper. Place a sheet of parchment over top of the print. With a parchment pencil filled with melted chocolate, trace the butterfly with chocolate.
To make a parchment pencil:
Make a parchment triangle: Cut a 12-inch square piece of parchment paper diagonally in half, either with scissors or by laying it on a cutting board or work surface and slicing through it with the tip of very sharp knife, to create two triangles. You will use only open triangle; save the other for the next time you need a parchment pencil.
Make a parchment cone: With one hand, hold the triangle in front of you with the point facing down. Use your hand to wrap the paper around itself into a cone, come around twice to use up all the paper.
