Using a four feet by eight feet (4 x 8 ft) sheet of double wall cardboard. Divide it in half longwise. Now there should be two separate pieces two feet by eight feet (2 x 8 ft). |
 |
Measure and mark 6, 12, and 18 inches so there are four equal widths and draw a line the length of the card board. |
 |
Score these lines without cutting through the material. The card board will now bend evenly to give a rounded tree trunk look and stand without props. |
 |
Lay the piece down and measure four feet from the end to find the middle.
Mark a line across the middle and score along that line so the tree can be folded in half and stored when it is completed. |
 |
Gently apply the spray foam insulation moving in a moderate pace so lines are thinner, bumpy and ununiformed. Begin at one end of each row and move down the tree longwise. |
 |
Be patient and allow the foam to completely dry overnight. |
 |
Move the trees to be painted by standing and opening them. Use long spray streaks of matte finish paint. |
 |
Colors should vary; primer brown, brown, dark brown, green and light green, gray and black. If you cannot reach the top of the tree, turn it upside down and finish painting. |
 |
Let it dry completely before cutting through the foam along the middle line. Fold and store. |
