I found that you need a very sturdy table that helps eliminate most of this problem! I went to a second hand store and purchased a old computer desk,,,,the kind that has a little shelf that pulls out for the key board... and it works wonderfully! Next my hubby drilled a hole about 3 inches across, on the side ( about 3 inches down,) so my sewing cord could be plugged in on the underside of the desk instead of going behind the thin backing, he even cut out a rectangle in the backing that matched my outlet, so my new table sits flush against the wall! Hope this helps
