I use a pin, stuck parallel to the foot but set where I can leave it in while I sew, to keep my fabric from shifting toward the end.

I find I need to slow down the last few stitches of any seam when piecing; if I go to fast, I will veer off the line.

I usually keep the bulk of my hand on the fabric at that point but also keep the index finger of my left hand riding gently along the left edge of the foot to help stabilize the fabric. IMO, if you're not hanging onto that last bit for deaf life, it will wobble!

I never use a walking foot, I just sew at a slower speed.

I went to a retreat several years ago and found that I had left my regular foot at home and all I had was the walking foot so I used it and have never gone back to the regular foot. It feeds my fabric through so much better and it is easier to sew 1/4th from the edge.

I agree my machine is Pfaff always because of the IDT. And I leave it most of the time.

That is why my stiletto is my best sewing friend!

Until recently I only used my walking foot for quilting, sewing on binding and making bags with foam or multiple layers of batting. One day on a hunch I used it to sew my diagonal seams on 4 at a time geese and 2 at a time HSTs. I noticed a big improvement. I think the fabric had been stretching ever so slightly as I sewed along the bias when I used a regular foot. When squaring up the blocks the diagonal seam would not match the diagonal line on the ruler, mainly at the starting and ending points. Just a smidge but really annoying. Using the walking foot has pretty well eliminated that problem and I will continue to use it for any bias seams as I am quite pleased with the results.

As a footnote I did mess around with the presser foot tension before I went to the walking foot but that didn’t solve the problem.

Me, too! Never turn it off, but then I do simple straight stitch mostly.

I have a new Janome (6650) and it's giving me the same problem. I've adjusted to it, but don't like what I have to do. I'm thinking about going back to my old Pfaff 7550 with IDT for piecing and using the Janome only for quilting. If you have a walking foot, give it a try.
