Firstly, I'm never gonna get through one cone of 3000ft/meters so I'm not gonna buy two but this is the way my mind is going. Just have to strip some off the main cone for bobbin winding. In the dark recesses of my mind I'm sure I remember seeing a hand winder somewhere, possibly from a hand sewing thing, maybe even for wool. I will investigate, I just thought I'd ask because it's a thing that's common to all of us and it can't be difficult to come up with a cheap hand operated doohickey that will do the job for cheap.
