May I slightly hijack this thread (to avoid posting a thread for just a small question)?
What is the thickest wire you can still wind by hand 'nicely'. So it's not too stiff to stack up nicely and bend well.
I have used 0.2mm wire, which is incredibly flimsy of course, but stacks and bends perfectly, and had 0.85mm wire, which is just about workable by hand, but it doesn't play very nice, doesnt bend or stack super well.
I have been eyeing 0.6mm wire, which is about half the volume of the 0.85mm going by my maths, but I wonder how 'workable' it would? Before buying it as its not cheap.
