Here is another of the Christmas trees, this one slightly more difficult than the last one. I am not really sure of the creator this model but I had found the tutorial on youtube. This model does require glue to hold the layer together. There is a slight variation to this as well, one that does not require glue, which I will post soon.
Thick paper, works well for this model. Printer paper works fine and so does this thick wrapper paper.
