Do not pull the material forward or backward, but hold the two layers slightly taut and firm at the back and front of presser foot. When you are nearing the end of the stitching line, stitch slowly with right hand on flywheel and left hand on work. Stop the machine in time so that you do not sew beyond the cloth. Have the take-up lever at its highest point to avoid unthreading the needle when beginning to stitch again. Raise the presser foot and pull the material straight back with threads under the presser foot to avoid needle from bending.

Pulled wool can be removed by treating with a depilatory that loosens the fibers and permits them to be pulled away from skin without damaging the hide or it can be loosened by the action of bacteria on the root end of the fiber. Pulled wool when used is usually mixed with fleece wool before processing into yarns and fabrics.
