@Invisible: It's not that hard.

I've actually never tried. These days I mostly cheat a bit by wrapping the paper around a pencil and then packing it from the top with a flask funnel. It gives you a lot more control on the consistency and density imho

@Invisible: Oh, that made me sit up and take notice. Consistency and density are very important. My compliments. :)

Because it's an art and having a perfect joint is great
