I have several bobbin boxes which fit 25 bobbins each. I fill one box with bobbin thread and an other with a neutral Gutermann 100% cotton which I use for most of my piecing. If I need black or grey I'll wind a couple of bobbins. I like to be able to change the bobbin as soon as the one I'm using runs out, especially when doing embroidery. I usually wind another box full when I get down to the last couple.
When I only did sewing (clothes & household) I use to get fed up with stopping to wind bobbins. As I now have 5 Janome machines (2 are sewing/embroidery) I own over 100 bobbins. I can always find one for any purpose now.
I do like to use my 6600 to wind my bobbins. It seems to fill them faster than any of the others.
