I have sewing accessories in many containers, but right next to my machine I have a 12-inch turntable with room for lots of things, but the centerpiece is a rubber circle bobbin holder. It holds more than a dozen bobbins a all sizes to fit all my machines. I have any bobbin I need right at my fingertips including empty ones that can be grabbed and filled without leaving my chair. The center of the circle ends up holding assorted spools of thread as them come off the machine so I don't have to pop up and replace them on the wall-mounted spool holder ( I say "ends up" cause I never intended this, it just happened cause it is within reach.) The turntable also holds thread snips, a pair of scissors or two, a packet of machine needles for the next one I break, several little fabric snippets for use at the beginning and ending of strip piecing, etc. Hard to believe one foot-wide circle holds just about everything I need while quilting.
I think this "it just happened this way" organization demonstrates what really works for any one person. You can buy all the organizers on the market, but when you have been sewing for hours at a time and are fully involved in what you are doing, you should loook at the state of your surroundings when you take a break and see where you have placed things while you have been concentrating on your creative endeavors. Odds are, you intuitive organization works for you better than any "system" you can try to implement.
Maybe for some people, the intuitive system will just yield a mish-mash, but I bet others will find as I did that your brain will organize the things you need to make them available to you when you need them.
