Four 12″ x 12″ blocks which together form a 24″ x 24″ photoquilt. Typically a new design begins with four blocks, which together are called a maquette or sketch. If the maquette is sucessful, a design may become a full-size photoquilt. Many maquettes are available for purchase framed or unframed. Contact me for more information at chris.mercerhill@gmail.com.
