The members here on the QB are so inventive & clever that I was hoping someone has come up with an alternate material that could be as good as the Supreme Slider. I just find it so expensive (here in Canada it runs about $35.00-40.00 for the regular size) & the queen is even more pricey. Does anyone have any ideas as to what I could use instead of the Supreme Slider. Any & all suggestions would be very much appreciated. Tks to everyone.
