As with the method for sewing by hand, the first thing to do is to clean up the hole or rip by trimming away any loose or dangling threads. Take care as you do this and try to be as precise as possible. Threading the needle on a sewing machine can be a bit tricky as they use two sources of thread, one from the bobbin and one from the spool. The first thing to do is wind the bobbin so that it is wrapped with thread. Once the spool and bobbin are in place on the top of your machine, unravel a few inches of thread towards the far left side of the spool and wrap it around the nubbin on the left hand side of your machine. Then pull this thread to the bobbin, thread it through the small hole, and wrap it around the bobbin a few times to secure it. Fix the bobbin in place by pushing it to the right and then gentle press down on your peddle to wind the thread from the spool to the bobbin until you have as much thread as you need on the bobbin. Cut the thread to separate the spool and bobbin, then remove the bobbin and switch off your machine.
