Fleece threw tension off?
 

Help! I recently had my 1979 kenmore fixed by an OSMG, and the straight stitches were perfect and I pieced a quilt on it. THEN, I sewed three fleece garments on it, and now my tension is off... It looks like my bobbin tension needs tightening, but I don't think I know how to do it (it's a horizontal bobbin). I tried lowering my top tension but that didn't help. Here's a picture of the top...can sewing with fleece throw the tension off?? And... when I rip out the stitches - it's almost like pulling chain stitches -- seem as though the stitching is not tight. Anyone know what's going on?

I don't know if it's the fleece or not but it does look like the bobbin tension needs tightened. I'm not sure how to do that on your Kenmore. Is your bobbin threaded correctly? I know I'm guilty of occasionally forgetting to put the thread thru the little slot where the bobbin drops in on my Singer.

Could your bobbin area need some cleaning ..........fuzzies from the fleece material?

If you post a photo of the bobbin area, I should be able to give you an idea of how to check and adjust the tension. I'm thinking it's more that there's some lint holding the tension spring too far away from the body of the bobbin case though.

Cleaning the machine of all the lint would be a good start then let Tammi tell you how to adjust anything that needs to be adjusted.

when I sew with fleece my bobbin area gets alot of feece lint in it. I have to clean quite often.

Okay...I'll clean the area, and then let you know if it sews better...thanks for your comments.

I'd agree that your problem is fuzzies from the fleece that are where they shouldn't be - and that can include under the spring part of the bobbin case. I've actually had that happen many times with my Viking (main machine) where I've had to lift it up just enough to blow it out good - and then it works fine. That is the very first thing I check when all of a sudden my bobbin tension is way too loose.

Before you adjust your bobbin tension , try changing needles.A dull needle can cause these problems,also.also ,if thread isn't wound properly on bobbin, can cause this also. Hope this helps.

were you using a ball point needle?
