They have a variety of fabrics and notions for you to choose from. They are located in San Francisco so if you can't make it to the store, buy online. If you're wary about buying online, they do have 2" X 4 1/5" swatch services for $1 each when we last checked their website. They offer free domestic shipping for the swatches but you should check their shipping page for details.
