I for got to save the blog where I got this idea from. You are supposed to use double-sided paper, but I didn't have any for Christmas. Cut 3 squares - 1 each of 3", 2 1/2" and 2".
Fold each square diagonally both directions, then from side to side both directions.
Hold it folded in 1/2 in front of you, fold both sides in to form a triangle.
Insert and adhere the largest triangle into the bottom of the middle triangle, adhere those into the bottom of the smallest triangle, then adhere to your card.
I cut the truck out free hand and the star was a punch (now discontinued).
