Edyta Sitar's Signature Style Thread Collection from Aurifil is a must-have for those looking to stock up. This 12-spool collection features Edyta Sitar's absolute must-have neutral colors. Each spool in the collection holds 1422 yards of 50wt Egyptian Cotton thread. Mercerized to give it strength, this 2-ply thread has a lustrous sheen. Aurifil's 50-weight thread is a favorite for quilters as it holds tension consistently and is strong enough for quilting at high speeds. It is even smooth enough for hand quilting and mending. The long-staple cotton and mercerization guarantee that the thread doesn't catch on the fabric and jam up on itself. Colors featured in the Signature Style Thread Collection include: 2315, 2309, 6722, 2000, 2324, 2370, 2310, 2405, 6724, 2600, 2847, and 2605.
