The single spools of Aurifil at Thristan are not being replaced. The grab bags or door crashers are the better buy. 12 wt thread is perfect for hand embrodiery, better then floss. It's a thicker thread and adds texture to fabric. Tristan stocks Genziana cotton thread which is the same as Aurifil. Just different names. I have emailed and bugged those nice people with many questions. I learned a lot.
