Abstract
This disclosure relates to spool holders for supporting a spool of thread on a sewing machine and particularly relates to a detachable spool holder having spaced depending leg-like portions formed of resilient material for insertion into associated spaced apertures in the cover of the sewing machine so that the spool holder may be readily assembled onto the sewing machine frame and held in relatively tight fitting relationship therein while giving the appearance of a unitary structure.
