I do the black, white and beige and keep them in those donuts

I use pre-wound bobbins for my embroidery machine, but for quilting I wind my own.

My machine (Janome 6600) has a separate bobbin motor so I can wind bobbins without stopping or re-threading. I tend to buy pairs of spools of neutral thread for piecing, so I can keep one spool threaded up and then wind bobbins from the other spool as I need them.

When winding colors onto bobbins, I wind as many bobbins as I think I'll need plus one extra. I like to do crazy quilting with decorative, randomly-colored stitches, so those bobbins always get used up eventually, either as the top or the bottom color in a crazy quilt.

Pilgrim, I'm curious as to where you found the special attachment to vacuum your machine? I'm sure mine would be happy to have a friend like that! LOL

I have separate bobbin boxes/holders for four of my machines. I piece on my Feather Weight and use a neutral thread and fill 10 bobbins at a time. I fill fewer for my Kenmore, Brother and Singer but always have at least 3-4 filled bobbins for each.

Before I start a project I wind 3-4 bobbins so I don't have to do it again, it also helps me keep count, when I have used two bobbins it is time to clean.

When I'm getting ready for a sewing group sew day, I usually fill at least 4 bobbins with whatever top thread I'll be using. I put the filled bobbins in an old pill bottle.

Beige, white and grey. 10 bobbins at a time depending on the tone of the top I'm working on. I have a thingy that holds either 2 big spools of thread or (more often) a big spool of thread and a bunch of bobbins that I prewind.
