No go - I spent an hour going 5 inches, cutting the bobbin thread off every 1/2" or so when it jammed, removing the slide plate, cleaning the bobbin area, re-threading the bobbin - everything I could think of! I would sew a 1/2 inch or so then it jammed up - had to cut the bobbin thread off underneath due to a huge mess. I switched to a 50 weight DMC thread and didn't have any issues at all? I really wanted to use metallic thread on a little Patchability I was doing!
