Download the Grinch template, print, and cut out the pieces you'll be using.
Assemble the Grinch's face by gluing his eyes right below the eyelashes. Take the completed face and glue it to the paper bag flap.
Next, glue the neck strip on the main part of the paper bag, just below the flap. Place the Santa suit body just underneath the neck and glue in place.
Take the Santa suit trim and glue it where the neck and suit meet, so you only see the Grinch neck.
Make his Santa hat by gluing the trim to the base of the hat. Next glue the pom at the tip of the hat.
Finish off Mr. Grinch by gluing the Santa hat to the top of his head, slightly overtop his eyebrows.
