I was wondering if anybody can advise me on the threads you use for stippling. I was advised by my local quilt shop to use Mettler quilt thread on the top and bobbin fill in the bobbin. I am using white in both top and bottom. I am finding it is not stippling evenly and missing stitches. It is also knotting every now and again at the back. I just got my pfaff sewing machine last week after it has been serviced. I have always known that I should have the same weight top and bottom and I did question this at the time but they said it would be fine.
Would appreciate any advise
