Curated just for Sewing Parts Online, the Aurifil SewCreativeLive 5 Spool Thread Kit features our signature colors, red, white, and black. This collection has three spools of 50-weight thread and two spools of 40-weight thread. Aurifil's Mako Cotton Thread is a 2-ply, long-staple Egyptian Cotton that has been mercerized to add strength and a lustrous sheen that is not typically found in other cotton threads. The 50-weight spools (orange top) hold 220 yards and are the most versatile and popular cotton thread, perfect for quilting, English paper piecing (EPP), machine embroidery, applique, and much more. Mako Cotton thread in 40 weight (green top) is slightly thicker than a standard thread and is ideal for serging, bag making, topstitching, and garment sewing. Since the 40-weight is somewhat thicker, each spool only holds 192 yards. Our SewCreativeLive 5 Spool Thread Kit will quickly be your go-to set and is a must-have for every sewing room.
