I've got a box of hand quilting thread, but mine probably about 35 years old. I have that brand, but it clearly says "Hand Quilting" on it. It's also a plastic spool
This was mostly from my Mom, some I acquired buying boxes of sewing stuff at garage sales. I won't be doing any hand quilting, and it sounds like it should not be used for anything else.
I have a lot of vintage thread on wooden spools, and most of it is rather easy to break. Putting that on a rack for display would be a neat idea. Most of that came in sewing cabinets and stools.
