[quote=ktbb]my first guess is that for some reason the feed dogs are not moving the bottom fabric thru...that assumes of course that the top stitches look fairly normal...did you by any chance drop the feed dogs and forget to raise them again? what is the difference between the bottom fabric and the top fabric - any difference at all? are you using a walking foot to do this stitching?
Yes, the top stitches look fine. My feet dogs don't raise and lower, I only have a reg. machine. There is no difference between the top and bottom fabric, both are cotton........good quality fabric from a quilt shop.
No, I don't own a walking foot. I didn't have one when I made my runner either, that's why I thought I could do the placemats. I'm only doing stitch in the ditch.
