Assemble the paper lanterns. Cut out a circle from coordinating tissue paper that is the same size as the smaller opening in the paper lantern. Cut another larger circle around the first circle that you made. Glue the tissue paper ring around the smaller hole in the paper lantern.
Cut smaller white tissue paper circles and even smaller black cardstock circles for eyes using the same method you used above. Glue them onto the paper lantern near the opening where you glued the circle, which is the fish’s mouth.
Fold a piece of coordinating tissue paper and freehand a wavy fin shape with a flat bottom. Glue the two pieces together with a glue stick EXCEPT for the bottom inch. Fold out the flap of the bottom inch, and add glue to the inside of each flap. Attach the top fin to the top of the fish craft by pressing the flaps down so that the fin sticks up.
For the side fins, simply cut out two matching small fins out of tissue paper and glue them to the side of the fish craft with a glue stick.
For the tail, double a piece of tissue paper, and cut out a medium-long tail shape. Glue the tail together with a glue stick except for the top couple inches of the tail. Put glue on the inside of the two flaps at the top of the tail, and press onto the back-center of the fish craft. To hang, simply poke two small holes in the top, and pull through some string or fishing line.
