I am with you, I hate the threads all over and tangled. I found Thread Socks at Joann's Fabric store. It is plactic stretchy netting that you cut to the length you need. I keeps the threads under the netting and keeps order. You could probably find it on Amazon if Joann's are out of it. Works great. Amazon also has all kinds of different size plastic bags that can fit your thread and matching bobbins. I also have seen a rubber band wrapped around twisted around both. Joann's has small plastic cases with ajustable deviders/ or you can cut cardboard to fit inside what case you already have.
