Longo and Haggard put people's hands under a surface and then asked them to mark on the surface where the ends of their fingers and knuckles were. They found that people's representations of their hands is distorted by an underestimation of hand length and overestimation of its width. This distortion isn't uniform across the hands (less distortion for the thumb and index fingers than the others), which maps on to people's sensitivity across the hands. Interesting to consider why we should underestimate in one dimension and over-estimate in the other.
