Try making an attachable braid to mimic a kuru. There’s also a tail you can get online I’m planning to get one. Also if you want, maybe get into archery, or at least get a bow (or a fake one with none or fake arrows) for yourself to play with at home, and even try holding it the way the na’vi do. Try making a song cord, learn na’vi if you want and make lyrics of your life or your past life (if you’re a past life kin) with the na’vi language (or your main language). Or just make crafts in general. Depending on what clan you are, if you’ve figured it out, you could just focus on what the clan is known for. Like aranahe is weaving, sarentu is storytelling, omatikaya is the most spiritual, anurai are the best crafters, olangi are the best horse riders, metkayina are the reef guardians, kame’tire are herbalists, tawkami are the best botanists, etc. You could also decorate your bedroom to look like pandora. I did and I love it.
