The Genziana Cotton Mako cost a little more then the Aurifil on the website but I think it's because the Aurifil is being sold cheaper to get it out of the warehouse. I have giant spools of the Aurifil neutral colors when the site first put all the Aurifil on clearance some years ago. I can remember when Aurifil was first introduced to the US at quilt market. It was on QNTV online. I thought that sounds like great thread so I started searching online for a distributor and found the Tristan site.
