So I finally decide it's time to learn how to use the binder after having the machine for almost 3 years.

Get the binder all set up, manage to get the folds reasonably aligned and stitching in the right spot but I ended up with skipped stitches and a teeny tiny stitch length even though it was set at 4. Change the needles and test stitch on 5 layers of fabric (same as the binder strips would be) and get a perfect stitch. Cut another strip, insert into binder and I'm back to teeny tiny stitches, but not any skipped stitches. One small victory there. No matter how I adjust the tensions I can not get the stitch length right.

Extra info- Janome binder and plate, regular thread in the needles, serger thread in the looper, thread nets on needles, no thread nets on the needles (I tried both ways) foot pressure is the same (loosened) as I use w/knits. Settings when I stitched through 5 layers (minus the binder) were Needles 4, looper 3, differential N, stitch length 4. Perfectly formed stitches. Adding the binder into the equation is the problem.

Thoughts,suggestions appreciated.

Debbie

Try increasing your foot pressure

I had to think about that one for a minute. Not enough foot pressure and the feed dogs can't grab and pull the fabric along resulting in small stitches. I write that because I'm the type that likes to know cause and effect.

Thanks. I'll give it a try tomorrow morning when I can stitch some samples again.

I tried adjusting the foot prerssure from minimally to full pressure and everything in between with little change in the stitch length but slightly better looking stitches on the back.

Anyone have any other thoughts or suggestions?

I'm not an expert, but I've found that if the unsewn binding strip is hanging down I get terrible results, but if it's piled on the table everything works great.
