This, here, is what two and a half hours' worth of spinning looks like on the bobbin:

The thread is about 0.5 mm in diameter and has a twist angle of about 45° - at least that is what I'm aiming for...
Not very impressive, right? However, this means there is a lot of space on the bobbin for yarn - which is good, because it means I can spin a really large batch at once and thus have a very long continuous thread, nice for warping.
I'm already curious to find out how many metres will fit onto that bobbin if I fill it up... and I'm pretty sure I will be able to fill it up, as a good 3 kilometres of this yarn have to be spun.
