A sewing machine table thread stand plate is an accessory that holds large, cone-shaped spools of thread for smoother and more consistent feeding into a sewing machine. It is separate from the sewing machine itself, typically featuring one or more vertical spool pins mounted on a stable base or a plate that can be attached to a sewing table. The stand helps prevent thread tangles, breaks, and tension problems, especially when using thread cones that are not compatible with a machine's built-in spool holder.
