Serious quilters and sewers, this New brothread collection is exactly what you need for your projects! You get 18 spools of high-quality 100% mercerized cotton thread in 12 neutral and jean colors that cover all your basic needs. Each spool contains 600 meters (660 yards) of 30WT thread (50S/3), which is slightly thicker than standard sewing thread - perfect for quilting, machine embroidery, and heavier sewing projects. The mercerization process gives the thread less lint, a smoother surface, and beautiful matte sheen while increasing strength. What's really clever is the spool design with locking bases that prevent thread tangling and unwinding - though you might need a thread stand if your machine doesn't have horizontal spool feed. This thread works beautifully with natural fabrics like cotton and linen because it has similar shrinkage rates, preventing puckering after washing. New brothread has been in the business since 1988 using German and Italian technology, so you know the quality is professional grade. Just remember to use larger needles (80/12 or bigger) since this is thicker thread, and slow down your stitching speed as cotton doesn't stretch like polyester. Whether you're piecing quilts, doing machine embroidery, or general sewing, this thread collection delivers consistent, reliable performance project after project.
