It is gathered together on one side. When I lay it flat on the floor its triangular but bunched at the gather. I've tried putting the gather on a hook and pulling from there. I've tried a corner. It's weird! Should I remove the little thread that gathers it in the one spot or should it stay there. There were no instructions. I've surfed the net for 3 hours to find a picture ot instructions and have had no luck - thanks Kelly
