Print predrawn template pieces for the leprechaun body, hat, arms and legs on sheets of 8½-by-11 pieces of white paper. Cut out each piece; these are your tracing templates. You can also mount them on soft cardboard to make sturdier tracing templates. Print a colored version of the leprechaun face template on another 8½-by-11 piece of paper, and cut that piece out.
Trace the leprechaun hat, body and arm templates on green sheets of construction paper, and cut out all pieces. Trace leg templates on black construction paper, and cut out both pieces.
Glue the printed leprechaun face onto the body piece so that your leprechaun's head (face) sits proportionally atop its body. Glue the leprechaun's hat onto its head. Position the hat as you wish. Glue the arm pieces to the left and right sides of the body, and then glue the legs to the bottom portion of the body template.
Allow your leprechaun to dry for at least 24 hours to ensure that glued pieces will not come apart. Once your new leprechaun is dried, you may display it on your refrigerator or bedroom wall for others to admire.
