I have a pfaff 2040 and am having problems with the stitches skipping. Some fabrics, flannels, do better than others, less expensive cottons. While doing a straight stitch or blanket stitch I can't get the top thread to connect with the bottom and lock. Any suggestions? I have re threaded, changed thread spools, cleaned dust from the bobbin area, and oiled. Please help!!

I believe it is recommended to hold each thread until the stitching gets started, see your manual. I make sure the slack is removed from each thread just before putting the presser foot down, then just put a finger on the threads, clamping them between your finger and the sewing bed, until a few stitches are done. This can be done through the material being sewed.

It sounds like the problem is actually with the needle thread, remove the spool from the machine, raise the preser foot to the up postiton and the rethread the machine.
Good Luck!

You need to adjust the tension of the stitching, it sounds as if the top stitch tension is looser than the lower in the bobbin.
