Suggested fabrics: Make Bertha in wide-wale or pincord cotton corduroy. Light wool (with a checked pattern) or denim (cotton) also work well with this pattern. Choose a fabric that has enough drape. If you decide to go with corduroy or denim, don’t forget to wash your fabric before you start cutting, as these fabrics have a tendency to shrink lengthwise.
