Aunt Maggie primarily uses real sheep's wool from Canadian companies. It makes warm garments that last, and comes in a rainbow of colours for every taste. The collection is always changing as these wools are made in limited dye lots that can vary slightly from other batches. In her enthusiasm for new wool, some items are made with other types of wool, or wool blends. Please contact Aunt Maggie for availability. Wool should be hand washed with mild soap in warm water, and placed flat to dry. My primary supplier is yarncanada.ca, if you prefer to search for an option you like directly from their site.
