A spin-off Yahoo group from ArtErratica called ArtBound was started by Michelle Cardoza-Takas who originated the Little Fat Art Books. From there a spin off of ArtBound was created by Bernie Berlin called Artbound2. After that many other artists have sponsered fat book Yahoo groups. One such artist is Tracy Roos who created chunkyland.

Fat books are books of 4" X 4" square pages created by 55 to 65 artists who share their work with each other. Each artist makes multiple copies of his page (either originals or photo copies) to be collated, bound, and distributed by the host or hostess to all players. Usually the book cover is provided by the host or hostess.
