I really like the bobbin savers (round rubber donuts). I have three in different colours. One for each of my two machines, and one for pre-wound bobbins that fit both machines. I rarely wind bobbins anymore, prefer the pre-wound ones from Superior Threads. My regular bobbins mostly have decorative thread on them these days.
My thread is stored out of the sunlight in a drawer for the larger spools, and in a nifty plastic container with two layers from Pep Boys. Just the right height for most spools.

bobbins in the donut things for when I need a color/matching thread
neutrals for pieceing for in a tube

threads are in one of those three drawer units out of direct sun and protected from dust.

I have four thread racks I got at Joanns and a little bitty bobbin rack that looks like a mini thread rack. They are all hanging behind my computer. It's next to my sewing table in the dining room.

i just got this bobbin holder for 12.00 it holds the bobbins with out the thread hanging all over and it comes apart if you need it too. the thread on a thread rack

I have several of those big plastic three drawer things and they are full. Red in one drawer, etc. Then I also have a thread rack for what I am currently using, and what I have not put back yet. Then I have all my embroidery thread, (machine stuff) in special clear containers. Well, that is the small sizes, the bigger ones are in another drawer thing. Then all my serger thread is in a big dresser drawer.

And guess what, I really need to buy actual cotton quilting thread. I have been trying to use what I have and not buy more, but I have mostly blends so I guess I should buy more. Is that crazy or what?

Never thought of using pony tail holders!! Thanks for the tip! :thumbup:

My bobbins are in the storage space of my machine. I only wind what I think I'll need for a project in either black, white or beige.
Thread is in ziplock bags in a basket. Regular thread in one bag, specialty threads in another.

I buy the cone thread since I have a serger and I store it all in 3 drawers (the plastic kind on wheels) and my bobbins I store in a doughnut shaped plastic container. I think I need to get one more though just for my quilting threads!

I made a holder which has room to hold the spool of thread and it's matching bobbin. It's made from a piece of acrylic, which I drilled holes into, then added acrylic rods. Here's a pic of it. I made it to fit inside a drawer.

VERY COOL
