bobbin tension? not catching stitch in FMQ
All of a sudden when I FMQ the needle will seem to jump and I'll have a stitch that's an inch or so long. If I keep running the machine it will eventually catch and the normal stitches will start to appear. I'm going crazy trying to fix this. No problem with straight sewing. It's as if the bobbin thread is not catching for a stitch or two. I've taken everything apart and removed the dust bunnies, threaded and rethreaded both top and bobbin.... even adjusted the top tension even though it doesn't seem as if this is the issue. I've read the trouble shooting section of the manual.... I have restarted - only to have these big stitches, have the thread break, even had the needle break - over and over and over again. I'm sooooo frustrated.
I'm using a Brother 9000 which has a top loading bobbin. On my older Brother there's a screw in the bobbin case that allows you to adjust the tension, but there's nothing in this to adjust.
Perhaps that's not even the issue ....
suggestions?

I think if the tension is appropriate when straight stitching, it might not be a tension problem. I think maybe you are moving your fabric faster than your needle. Does it happen when you FMQ a straight line or perhaps on a curve? When I took my FMQ class, I had this happen alot, especially when I changed directions quickly. Also, the instructor told our class that once you drop your feed dogs, there isn't any tension on the threads, top or bottom. . .

Good point - it doesn't have to happen on a curve, but it does happen there. I don't drop the dogs - I'm using an open toed darning foot and leave the dogs up. What's driving me crazy is I've done ... 5 - 6 table toppers and 3 lap quilts with NO trouble then on the last two ... many problems. Perhaps getting overconfident and moving fab too fast??? Slow hands; fast machine is what I'm aiming at.
Your post made me think - my previous projects were mainly meander, though I did one with a flower. This time I'm doing leaves with loops in between the leaves - perhaps this is more direction changes? Have to think on that one. The flowers went off without a hitch, but were more predictable movements....
Thanks for the input. I've put it all on time out and am doing some piecing - then I'll try again.

Recently (April?) Fons and porter had article on fmq and described this....it happens to me too. The lady said as you fmq the needle bends/flexes a bit because everything/fabric is in constant motion and thus the needle/thread timing can not catch resulting in skipped stitches. She said slow doen. There might have been a needle size change suggestion too. It was a good article. I read it in the bookstore but have been meaning to get a copy of it. Hope I described it ok.

Okay - did an entire block with no breakage or skipped stitches so Auntpiggylgn you solved the problem. NOW ... tell me how I was able to do the flowers and the meander with the dogs up?
I'm also going sooooo slowly - so both of you nailed that one. Getting over confident, I reckon!
