Wrap a piece of electrical tape around the rim of the clear plastic cup.
Next, you are going to layer a second piece of tape on the cup. But for this piece, cut some jagged areas and some fringe to give your Grapenstein a hair-do.
Wrap the tape around just under the first piece of tape.
Wash you grapes. Fill the glass half-way with grapes.
Cut a marshmallow in half. Be careful not to cut all the way through. On the sticky side of the marshmallow stick on two M&M eyes.
Put the marshmallow eyes into the cup.
Fill the remaining areas of the cup with green grapes.
Using electrical tape, cut a small piece to make the mouth and stitches.
