Attu women were the basket makers of some of the finest baskets in the Native American World. The traditional material for these baskets was a type of rye grass that grew wild throughout the islands and was carefully gathered and prepared over the course of several months. In early summer, women traveled inland to find the longest and toughest grass available.

Some baskets have over 1000 stitches per square inch, these threadlike strands of grass were so tightly woven that the texture of the finished baskets has often been compared to linen..
