Use a ruler and pencil to measure a 2 x 6-inch rectangle on a piece of colored card stock. Cut out the rectangle with scissors to create the base of the bookmark.

Use a hole punch to make one hole near the center of the top of the bookmark. Be sure to leave a little space between the hole and the edge of the card stock so it does not tear.

Take one pipe cleaner and cut it in half. Thread both pipe cleaner pieces through the hole at the top of the bookmark.

Twist the pipe cleaners together near the hole to help keep them in place. Bend, curl, and spread out the ends to make some crazy monster hair. Set the bookmark aside while you make the face.

Place a dime on a piece of white card stock and trace around it twice with a pencil. Cut out both circles to make the monster's eyes. If you want to give your monster three eyes, or even more, simply trace and cut out a few extra circles.

Use the hole punch to punch two small circles from black card stock. These will become the pupils for the monster's eyes.

Add a small amount of glue to the back of each black circle and attach one pupil to each white eye. Let them sit for a minute so they do not slide around when you attach the eyes to the bookmark.

Arrange the finished eyes near the top of the bookmark, just below the pipe cleaner hair. Glue the eyes in place. They can be lined up evenly, tilted in different directions, or placed slightly crooked to give your monster a funny expression.

Use a pencil to draw a row of jagged monster teeth on white card stock. Make the teeth pointed and uneven for a fun monster look. Cut the teeth out with scissors.

Glue the teeth onto the bookmark below the eyes to create the monster's mouth. Gently press all of the pieces into place.

Lay the Monster Bookmark flat and allow the glue to dry completely before using it in a book.
