Yes, electronic products need to work over a range of voltages as the mains is not maintained at exactly 240V or 230V. Typically they have a range of at least 10% and normally much more. So it should work down to at least 216V.
Yes, it can be and there is no problem at all Because most of the electrical appliances are made to work on 220v - 240v so it can also be plugged into a 240v outlet.
Yes it will. If you consider the variances in voltage that occur during the course of a day, at 230v rating you may be getting 240v coming in anyway. The 10v difference is less than 5% and any appliance worth it's salt will handle this no problem.

Sewing machines were invented during the first Industrial Revolution to decrease the amount of manual sewing work performed in clothing companies. Since the invention of the first working sewing machine, generally considered to have been the work of Englishman Thomas Saint in 1790, the sewing machine has vastly improved the efficiency and productivity of fabric and clothing industries.-Wikipedia

The Shark 80-Stitch Sewing Machine works with quilted material.
the tension is probably wrong. try tightening/losening it.
It is not advised as the sewing machine is designed to work with fabric, a much softer and suppler material than cardboard. You would risk major damage to your sewing machine and possibly voiding any warranty you may still have on it.
