Ready to glue it together? I have no idea in which order to do this. I folded and glued the bumpers first. Then did one side at a time starting at the roof. Finishing up by attaching the front and rear ends to the sides.
Measure the top of the roof side to side. Cut a piece of card stock this wide and as long as the space between your bottom side tabs. Test fit, adjust if necessary, glue on top of the folded tabs. (Figure G)
Now get out your colored pencils and fill in any white that is showing with the proper colors. (Figure H)
If you are really feeling creative, you can modify your model.
Change the color, add stripes, make side mirrors, change the tires and rims, add a number and make it a race car, cut out the windows and add an interior, open the hood and add a engine.
The possibilities are as endless as your imagination. Have fun!
