I will now be going back and tearing out a few of the skipped/shredded thread areas and quilt them back out. Since this was an old project that will just be living at home, I will not be 'reverse sewing' the whole section affected. If this was bound for a show, I would replace each and every affected area. I have not had issues with other 35 wt thread with a 90/14 so I don't know what the difference is with this particular thread. Perhaps it is a twist difference or the actual fiber from which it is manufactured.
Lesson learned: check for needle recommendations on threads. I had stitched out a test piece, but the problem didn't manifest in the sample.
What thread lessons have you learned through experience?
