Ok, so this isn't really a new idea, but I just saw some pretty cute stuff from Anthoropology so I thought I'd blog about it. They have metals, jewels and cute ceramic figures that add that special touch to you dresser or cabinets.
Another store that has really unique drawer pulls is Monkey Shine. They take vintage pictures, such as Alice in Wonderland, and put them on knobs. (See link section to find the store) But if you want to do it yourself then I suggest buying vintage and adding color. These knobs below were brass and I sprayed them white. Modern antique style.
