The problem with doing it all over again is the bobbin and tension on this machine. I have had problem from day one and it is a complete hit or miss if it will stitch correctly on any level. No matter how well you spool your bobbin or thread your machine I usually have to re-thread my machine more than once in order to get the tension to work correctly. It isn't the settings on the machine it is soley the machine and how it feeds the thread.
