Just a note: My dealer advised strongly (forbid) against titanium needles. They are stronger than the metal in the bobbin system and can cause serious damage. I purchased embroidery needles and in very small print along the side of the case it stated the needles were titanium.
Does that warning pertain to all sewing machines or just certain brands. I know I have some titanium needles and do not want to create a major problem by using them.
