Interesting how we all like something different. I'm sure my needle is the correct size as I've always bought what was recommended for my fabric and my thread and use that little slide test to be sure.
I have to clean the bottom of my machine out at least every half of a bobbin. Seeing as it was damaged in shipping I'm certain it has issues, but none of them can be fixed because the casting is bent. When my sewing machine dies it will be the end of quilting until my husband finds a job. So thanks but I'll just keep trying different threads until I find one that works all the time.
