How to Make Your Own Shark-Style Trunk-or-Treat Halloween Decoration

Lay (1) of the white foam core poster boards out on your large cutting mat, then hand draw a sharks snout. Cut along the marker line with the utility knife and set aside the excess. Lay the second white foam core poster board out on your large cutting mat. This second foam board will be used to make the teeth for your shark. Maximize the use of this poster board by cutting the top and bottom teeth out of the same poster board. Cut along the marker line with the utility knife and now you have the top and bottom teeth for your shark. Lay the (2) light blue foam core poster boards out on your large cutting mat. Use a plastic plate to trace around to create the top of your waves for each board. (Repeat this step for the (2) sets of blue and dark blue foam poster boards.) Cut along the marker line with the utility knife and set aside the top excess pieces. (Repeat this step for the (2) sets of blue and dark blue foam poster boards.) After each set of waves are cut out, tape the matching waves to one another forming a long wave to cover the width of the trunk. Then, stack the three separate colors in any pattern to create your faux waves.

Tip: Keep in mind the properties of foam core boards when choosing your paint. Solvents and lacquers will erode the polystyrene centers. Acrylic paint is really ideal because you do not need to use solvents. Acrylic is also fast-drying and durable. Paint the snout cut out with gray paint, use a paint roller for a more even base coat. This may take more than one coat of paint to get your preferred color consistency. Set aside and let dry for the amount of time suggested on the paint you chose. Also, paint the dowel rods gray to help them blend in. You can now bring in both sets of teeth, using the red paint create a gum line on the teeth. Set aside and let dry for the amount of time suggested on the paint you chose.

Drape a red sheet over the open trunk to help create a backdrop for the shark’s mouth. With the hot glue gun attach the top teeth to the snout and press firmly. Attach the two dowel rods to the snout with painters tape. This will support the snout and hold it up out of the trunk. Then, set the bottom teeth in front of the dowel rods and secure them with painters tape.
