Fabric
Contrast fabric (upper bag): Light to medium weight canvas, twill, medium weight linen, corduroy, poplin, quilting cotton, and light to medium weight upholstery fabrics. Since all main body pieces are interfaced, light fabrics can still result in a structured and sturdy bag. Main fabric (lower bag): All of the fabric options suitable for the upper part of the bag are also suitable for the lower part of the bag. If two fabrics of varying weights have been selected, use the heavier fabric for the lower part of the bag. Lining: Quilting cotton, poplin, medium to heavy weight acetate lining, flannel.
