I have an old Viking, 630, and it's funny you mentioned this. Just today, after having my machine for 20 years, I ordered my first walking foot, got the one from Husqvarna.
I tried it out, and it wasn't even making stitches, just thread lying there. It ended up I needed to loosen the tension on the bobbin. I've never fooled with the bobbin tension before either, but after I turned that little screw, no more problem with stitches.

When this foot came, it was packed with a little plastic pillow type thing, full of air for shipping. We had fun with it, it looked to me like this came all the way from Sweden. My one dog was sure interested in it, maybe it was air from near where a Swedish dog was!

Quilts are works of art, just like paintings. They are not meant to be viewed up close or with a magnifying glass. It is all that noticable when the quilt is on a bed and you are a few steps away? Sounds like maybe we have some of our priorities a bit out of order. By the way, according to Amish legend, only God is perfect. Are we trying to out-do God?

that is what was happening to me...............

What kind of fabric are you using? I recently was working on flannel, front & back. It pulls hard and may be a problem.

I used a scrap, 3 layers, of a cotton fabric, and there was absolutely no pull on the fabric. It was the bobblin tension, canged that, solved the problewm for me

I had just had my Bernina serviced and after a while I had trouble with the stitches again. When my daughter came for a visit, she said the thread on my spool was too tight and she put the spool on a thread holder. I have never had the problem again. It really has helped me a great deal. Hope it helps you.

Thank you all for your replies. I have a feeling that at times I probably am causing some drag on the quilt and not allowing the feed dogs to do their thing. I do sew very slow when I use the walking foot, but on my Viking I do not have speed control, so I can't always sew as slow as I like. On my Janome I am able to control the speed which is probably why those stitches are a bit more consistent.

That's interesting. I have played around with adjusting but not gone so low. I will give this a try. Thanks!

Interesting about the bobbin tension. I am just so leery about adjusting it though. Your dog is a little cutie!!!!

I don't know why I was leery of it all these years. You just turn a screw and if you don't like it, you turn it back!

I have a 40+ year old Elna. After trying the walking foot and trying everything I could think of to make it work, I gave up and went back to my floating foot. (At the time, I was taking a class....even the instructor couldn't get it to work.) Good luck with yours!!!
