I'm new to Free Motion and I just bought the Supreme Slider and the bobbin washers. I saw immediate improvement on the stitching being more regular when changing directions, which is what the washers help with. I have a foam table like others have described and use a large piece of oilcloth on top, which makes a good slick surface. But the new teflon slider thing covers everything except the needle hole and seems a little slicker than my oilcloth. I like the machingers gloves but they're a little hot for my part of the world.
