An apparatus adapted for mounting on a sewing machine for holding a thread end left in the needle after completion of a sewing operation, comprising:
- a tube having an opening at one end adapted to be positioned adjacent the needle of the sewing machine;
- means connected to said tube for causing air flow into said opening to draw said thread end into said tube;
- means operable in response to cessation of operation of the sewing machine for activating the causing means to draw said thread end into the tube;
