I do. Used to keep a supply of cotton string in the house, and I still have some, but now you can only get that miserable plastic stuff. I also have heavier twine.
String is an all-purpose essential. I keep it in a storage closet along with lightbulbs, gift wrap, vacuum cleaner bags, and other supplies. I tie up rolls of things, make temporary replacement cords, tie (not tape) jigsaw puzzle boxes, and sometimes hang things up with string. Way back when, it was also for pulling teeth, wrapping parcels for mailing, adjusting the fit of an overlarge (boyfriend’s) ring, and all sorts of other miscellaneous uses. Everyone should have some string.
You used to have to wrap parcels in brown paper and tie them up with string. Just ask Maria. They had to be openable and reclosable, not taped.
If you light one end of a piece of cotton string, it burns slowly like a coal, and you can use it to burn designs into pieces of tissue. It smells, though. I remember doing that outdoors on summer nights as a kid.
The heavy brown twine is in a kitchen drawer and mainly serves to truss up stuffed turkeys. I don’t know if there’ll be any more of those.
