Always a possibility :) . But I don't think it's me in this case, as I've no problems with any other threads, just these thicker ones. I did talk to the Janome dealer and Janome themselves about it a while ago, and they just said use finer threads.... I suppose it was unreasonable of me to expect a machine labelled "quilter's edition" to take machine quilting thread :roll:
