I put my package of Fairfield bamboo batting (50% bamboo and 50% organic cotton) to the test. The first thing I notice as I removed the batting from the package was how soft it was and how thin it felt. So, after pressing it against my face (LOL), I compared it to the cotton batting. The bamboo batting definitely feels nicer to the touch. As for the thickness, I would say it is about the same as cotton.
Next step was to place the batting into a warm dryer for a little spin to help remove the fold lines. I then draped it over the ironing board for a couple of days. Some fold lines remained, but not deep enough to worry about. After thread basting my quilt top, I began to quilt. It was not difficult to hand quilt and maybe even a little easier then with cotton batting. Because it is not as firm as cotton batting, I would think twice before using it for wall hangings.
Overall, I liked it! I like how it feels and I like that it is a green product. Availability is an issue. Right now the only place I can find it is across the border at Jo-Ann Fabric and Craft store. Sold in packages from crib size to king size. The larger the package, you purchase, the more money you save. Plus, Jo-Ann's has 40% off coupons. I don't cross the border often, but when I do, I will be sure to pick up more bamboo batting.
