I decided to try to some well known top stitching threads for my quilt for FOQ this year, they came highly recommended but of the three spools that I've bought one is causing me real problems. There are tiny slubs on what should be a smooth thread that cause a build up around the needle eventually tightening the tension and causing the thread to snap. Do I write off one manufacturer because of a one in three fault? (I'll be writing to them if there is any thread left at the end of the quilting!) Or do I try someone else, I think I've mentioned before that my machine seems quite fussy about which threads I use. I've a few to try yet - Mettler, Aurofil (Love the colours on the home page!) and the relative newcomer to the UK Wonderfil .
If you have a favourite, particularly if you sew with a Pfaff, I'd love to know what you use!
