Step 1
Lay the card that has the outline of the tree on a flat surface.

Take a ruler and line the edge of it up against the center fold line of the card.

Step 2
Use the rounded end of a paper clip (or a ball point pen that has run out of ink) and press it along the dotted line carefully scoring the card all the way from top to bottom. Score all the other dotted lines on the card as well.

Step 3
Cut the card out carefully following the solid, black lines around the edges.

Step 4
Begin to fold the card in half, keeping the outline of the tree on the OUTSIDE so you can always see it.

Step 5
Fold the card completely in half with the outline of the tree still visible.

Step 6
Carefully cut along the SOLID black line of the first segment at the top of the tree.
