Follow steps 1-30 of my "Here's the Venus" Tutorial to make ONE Layer (piece) of the Christmas Tree. You will need 5 pieces in total. Start with 5 squares of paper (a) 15x15cm, (b) 12x12 cm, (c) 10x10cm, (d)8x8 cm, (e)6x6cm, then simply stack the 5 modules with the largest on the bottom. There you have it!
