My PFaff (it's fairly old..a Tiptronic) has a special stitch. Hit the button and off it goes. It goes through one hole in the button three times and then it goes over to the other hole. I am able to manually use the wheel to make sure it won't hit the button...if it does, I just adjust the stitch length. Haven't hand sewed a button on for a loooonnnng time. Once you try it, you'll be okay with it.
