So it's well known that Anthropologie is a great source for fun and pretty knobs. (Remember my recent search?) But! yesterday I was at Cost Plus World Market and spotted a small but decent display of ceramic and glass knobs all under $5 bucks! I was able to pick up a pretty floral knob for $3.99 that I am happy with. Also, it looks like they are selling knobs in a pack of four on their website if you don't live close to a World Market.
