Well first thing first the tangle mess I went to see my local floralist, when her flowers come in they have a plastic strechy netting on them she saves them for me. (she use to just throw them away) I just slide them over the spool of thread no more mess and I don't have to take off the strechy thing to use the thread.
Next: I have 2 120 spool racks 1 for embroidery and the other for just thread. They hang on the wall just high enough fo me to reach the top roll' On the one for emb thread I wrote the color# of each spool under the peg. This way when I have the sewout instruction with thread I don't have to pull each spool to see the #. Both racks are covered with a piece of window plastic it is tacked to the top and just hangs down I just reach under and grab the one I want.
Hope this helps
