Goodness, some of the descriptions of sewing machines make them sound like frontal-lobe-challenged teenagers! I find that, whenever I think my machine is to blame it’s often me all along; the trouble is, for me, that there are always too many variables to be able to work out which exact thing it is that is messing up; it’s like testing for allergies - you have to eliminate one ingredient at a time. But that’s so difficult with sewing. Sometimes, when I think it’s the thread it’s actually one of many other possibles: tension, batting, fabric itself, oiling, worn out needle, worn out me....I agree with the ‘I’m not going to let my machine be picky’ philosophy, and anyway, as already said, it’s often I myself who am to ‘blame’. I personally love Superior threads and use different versions for most things. Amongst the muted whites and greys there are so many lovely shades, and in King Tut some really pretty variegated ones that can be beautiful in quilting, if a slightly heavier weight thread works.
