I mentioned on the post about my Peggy skirt that I had some issues with the topstitching.
It looks ok from the right side (bar a few skipped stitches on the sections where there are a lot of layers):
But pretty awful from the wrong side as you can see below:
Believe it or not, this is a distinct improvement on how it looked originally.
Based on advice from Twitter and Instagram, I switched from a denim needle to a topstitching one and used normal thread in the bobbin with topstitching thread on top only. I fiddled with the tension on the top thread.
These lessened the problem considerably but it's still not great. My machine didn't seem to have any issues with sewing the layers with normal thread, just with topstitching thread.
The only thing I could find online was that Gutermann topstitching thread (which I used) is apparently much thicker than other brands.
Can anyone shed any light on my problem? Any great topstitching tips to share? Have you found that the brand of thread made a difference? All suggestions gratefully received as I want to make jeans at some point and that's a lot of topstitching!
