The stitching seems to be doing a LOT better. I think the Towa gauge is helping and I also found that Superior Threads has a grid of threads and the recommended tension of the bobbin AND the top thread. They have a top thread tension gauge that I ordered yesterday.
I also ordered a set of Red Snappers! I saw these quite awhile ago but they were out of stock and I forgot about it. Can't wait to use them on the next quilt.
