Tristan Italian Thread the ones who introduced Aurifil to the US decided to clearance out Aurifil thread to go to another brand. (which is excellent thread too) The prices were unbelievable. I bought cases of 24 large spools at a time for about $65. Tristan has the Tre Stelle 100% Egyptian Cotton 50wt Thread now. I watch their website for specials. I got a spool of 10,000 yards 50wt in bronze color for $18. It's a great color for piecing.
