Thanks for all the good suggestions.I finally found the correct tension and was able to finish quilting my grandsons quilt. Now on to the binding. I have read about the bobbin case. Too bad you can't use the automatic thread cutter when you are using it. I sure love that thread cutter! I will definately get the bobbin case. I've never had a machine that didn't have a bobbin case. I was scratching my head, trying to figure out how to adjust the bobbin tension with no case.
You are all the greatest, to take time to help a fellow quilter. I'll post a picture of the quilt when it's finished.
The next quilt is a queen size for our son and ddil. I'll be ready to start quilting it as soon as I am sure the problem is solved. Picking out a mile of stitches is not on my list of fun things to do...haha
