I have a diamond sword now :D
And of course, I used glitter! I actually made it glittery by coloring everything with glitter pens, so it took a while. And I sealed it with tape to not mess up the glitter. But, I found out that I had not reversed the other side, so I had to remake the other side again. I know it's not perfect, but it's ok for the first try (it took me 2 days to make this one)
