Calico is a woventextile made from unbleached cotton. The fabric was first made available to Inuinnait through the Hudson Bay trading post which opened in Tree River in 1919. The fabric was rapidly adopted for Mother Hubbard style parka covers. While the early calico cloth available to Inuinnait was often conservative in design, fashion increasingly demanded brighter colours and more intricate patterning. Calico patterns today often have vibrant prints incorporating multiple cultural and geometric designs.
