Materials: I would most likely use a cotton duck canvas treated with a waterproofing spray (http://www.amazon.com/Armor-Fabric-Waterproofing-Natural-Fabrics/dp/B002WLUYUG). I don't need the bag to be completely water tight, but I know that rain is unavoidable and that my back wheel will be spraying the bottom of the bag with lots of water.

Skills: When I make this bag I intend to use the sewing machine skills that I learned in the class. Also, in the design process, I relied on the additional exposure to textiles that this class provided me with.
