At the moment she is trying to sew a nylon fabric with a thin foam backing incorporated to the original backing fabric from the old seat cover. The top thread simply isn’t catching and tying to the bottom thread.
Any advice or suggestions? Settings we should change, and in what direction?
I watched a video on Skill Shack (the site made by Practical Classics magazine), which advised the following, all of which we are doing:
- heavy duty thread
- size 100 needle (new)
- less foot pressure, since the fabric is thick
- they said to adjust thread tension depending if you got loops on the top or bottom of the fabric, but not what to do if you got no tie at all
