This origami Christmas Tree was created by myself in 2014. It is a modular origami and all the units are connected without glue. You can also attach an Omega Star (designed by Philip Shen) on the top and little Lucky Stars on the points (all without glue!)
Paper
Any paper can be used to fold this model, but I love the Duo Thai paper from Origami-shop because of its texture. You can buy it online and they ship worldwide:
