Quilts are different from blankets, comforters and bedspreads in that they are constructed of 3 separate layers of fiber. Machine stitching has taken the place of hand stitching that was common in the past. Quality thread is used to guarantee the strength and form of the cover.
1st Layer - A full woven backing will commonly consist of 100% cotton quilt fabric, fleece, flannel, or muslin. It has the same stitching detail as the 3rd layer and can be reversed to expose a solid cover.
2nd Layer - The middle layer consists of a batting that provides insulation for the spread. It is made from cotton, wool or polyester. Other forms have recently been introduced, such as bamboo fibers. This filling can be thick or thin, depending on how much insulation you wish to have.
3rd Layer - The top layer traditionally has several even pieces of cotton fabric sewn together that present a colorful display of a theme. However, one full piece can be used and stitched for a more uniform scene. Different types of material, such as polyester microfiber or cotton denim.
