Making ninja star and sword out of paper / at home

I have been making ninja and sword at home at first I keep making mistakes but I keep on trying but I waste a lot of paper but I don't care because I have heaps of paper lying everywhere. My first ninja stars were the ones that haven't got color on it. It took me two A4 papers the next one is a bit bigger it has the blue on it that ninja stars took me four A4 papers. It took me pretty long. The one that took the longest
was the one with the blue on it. The ninja stare that had the blue on it had a lot of folding and tucking things in. I had a lot of fun making it.
