Ooh yay thread shredding party! Im sewing the lace tree skirt edging from one of the oesd christmas collections and everything was fine until about 10000 stitches and between there and 15 ive had the thread shred on me 3 times. Last time this happened on a lace piece i fixed it by changing from the 75/11 needle to 90/14, so that means its heat and friction in the eye right? I slowed the machine down too and that didnt work. I think the titanium needles are supposed to help with that and this is in fact my last needle so maybe ill try those. This doesnt always happen though, which is weird and one of the times it was on the first layer of underlays not all the intersecting satins.
