Grab FIVE large popsicle sticks and TWO regular sized ones {this is per monster truck you want to make today.}
Lay the four large ones next to each other, one by one, on a flat surface.
Now grab your other two popsicle sticks and glue them the other direction to create a square shape.
Once all the popsicle sticks are glued together, set aside to let it all dry completely.
Repeat the above steps for each monster truck creation.
When dry have children paint their popsicle sticks however they like, while you cut out some wheels & other monster truck features from the cardstock.
To finish off the Popsicle Stick Monster Truck, glue the cardstock pieces in place as well as any other embellishments you see fit {think rhinestones, glitter, paper flames etc.
