I am looking for advice about top stitching with heavy wt buttonhole twist thread—-
I can not get the top tension on my Pfaff tight enough to stop it from looping on the bobbin side (I have also loosened the bobbin tension). I am using a #90 topstitching needle. I believe there is too much resistance in the needle’s eye. I vaguely recall that I have seen something in Threads or somewhere about using something to ‘coat’ a needle to reduce the drag on it.
Any advice or suggestions about how to do this.
