I first noticed it with the "Mystic Purple Garden" quilts - I'd quilt an area roughly 1 square meter, and the thread would snap. I's have to stop, clear up the mess on the quilt, re-thread the machine and then carefully restart, trying not to have a double-stitch mark where the restart occurred.
|As you can see, it's not just snapped, but scrunched up and shredded - leaves quite a mess on the |
quilt, fiddly to pick out and restart when this happens.,
I pulled out the machines user manual and read through all the things that might cause this - the only one I wasn't able to rule out was the possibility that there was something in the bobbin assembly which had developed a "spur" and was catching the thread. I was sick at heart at this idea, as would most likely mean having a service call - and possibly shipping the machine back to the manufacturer - which would mean being without the machine for weeks and weeks.
So I rang Howard, the dealer I bought it from and chatted with him. He offered several possibilities, but I'd already ruled them out. Finally he asked what size needle I was using. Well.. I looked - and I've been using size 16 needles all along. Then he asked what kind of thread: Superior brand. He told me he always uses 18 needs with Superior thread.
I have a few 18 needles - they came with the machine. As he suggested, I changed the needle from 16 to 18 and well, folks.... I'm back in business.
I'm not sure what to make of it - size 16 needles for nearly 18 months and no problems until just recently. It doesn't make sense, but there you are.
