I have the Supreme Slider. In fact I have three of them. One was a gift, I won one on a blog give away and I just bought the new extra large size one. I notice a big difference in my hands, they feel more relaxed after quilting. If I don't use the slider my hands feel tired. I rinse it in water to remove lint and threads and it resticks like new. I don't see how a baking sheet would work the same. I have a teflon baking sheet and it is nothing like the Supreme Slider.
