I made 3 quilts using Bamboo batting. I love the way it drapes and it is light but much warmer than cotton and gives more definition to the quilting. With the continued failure of foreign crops, 3 years in a row, we must look to other replacements. I favor hemp as a material. I don't know the problems but they are trying to use the rice leaf as a replacement for fabrics. Cotton destroys the natural minerals in the earth. It does not give back and you are supposed to alternate crops to replenish the soil but most growers do not. They try adding the chemicals and keep on growing. We must stop destroying our planet.
