Craft: Trivet from Wine Corks

I have made a wreath and a Christmas tree from wine corks, and all I did to prepare them was to wash/soak them in hot water and dish detergent, then rinse well, and let air dry for a couple of days. You do have to weight them down to keep them under water to soak them. I used a bowl and a plate as the weight. This did not remove wine stains, but they add character to me.
