I carefully threaded the needle and prepared to sew the hole in my son's jeans.
The first thing you should do if the motor is turning, is check to see if your machine is threaded correctly. Then check to be sure your bobbin is in and threaded correctly. If it still won't sew, check both your upper and lower tension. Adjust until the stitches are even and tight, but not too tight. See related link below for more information on adjusting tension.
