Aurifil is a brand name of thread. Genziana Cotton Mako and Tre Stelle Oro Cotton and Aurifil are all the same thread. I remember when Aurifil was introduced to the US quilt market a few decades ago. Two women were on several tv quilt shows at the time promoting the Italian thread being imported to the US. I buy Aurifil and Genziana here:
