This is an intermediate to advanced level sewing pattern. It involves sewing zippers, binding, interfacing, and sewing through many layers. It is recommended that beginners do a test run with quilting cotton to get familiar with the techniques. I also have a tote-style pattern that is perfect for beginners.
