HELP!!! Need help on a New Home Model 552
DIL has her Mother's New Home Model 552 sewing machine, has no manual on it and we are trying to turn the knob on top to change from striaght stitch to ZZ and other stitches. Is there a trick to this??? Also, do you know where we could get a manual? I have looked on internet and can't find a place that carries that model. Thanks
