Brushed cotton Quilters Flannel is a thick weight brushed cotton fabric. Ideal for use in making quilts, blankets and throws. Often used when sewing baby projects. Cotton Flannel is very soft and has a naturally warm touch. Brushed cotton can be combined with standard cotton and other quilting fabrics. When mixing fabrics it is always advisable to pre-wash all fabric to prep before sewing as this minimises any potential shrinkage. Prepping fabric ensures you get the best possible finish on your finished project.
