So I'm quilting along and suddenly notice that I'm having some serious skipped stitch issues. Oh bother. I change the needle, check everything, oil parts, change the needle again and nothing seems to be helping.
I finally check the stitching on a test piece of fabric, and it works fine. I am going through large seams some of the time, but it was skipping other places too. Anyway, I change the brand of thread (from Aurifil to Gutermann, in case you're interested) and everything cleared up right away. (And it is way past my bedtime. But it feels so nice to have the problem worked out.)
What do I do with the Aurifil thread now? It worked on the random fabric, so it might have just been having issues with this quilt. Save it for further quilting with a warning note? Use it for piecing? Trash it?
