Thread organizers have kept me sane and eliminated a great deal of frustration. Prior to using the organizers, I was always getting to a stitch-in, for instance, to find I left an essential thread at home. Sometimes I could work around the area, but often just had to stop.
That isn't a problem now that I've started using the thread organizers. It's such a good feeling to be able to pull out the project, thread organizer, instructions, and stitching supplies quickly. In a couple of minutes, I'm prepared to go to a meeting, stitch-in, appointment or trip!
Along with the thread organizer, there is a threader and a sheet of tabs to cut apart and insert at the top of the organizer for pertinent information about the contents of that partition.
