Schmetz Denim Jeans Needles Size 90/14 item # DEN-90
Made especially for sewing through densely woven materials such as denim or imitation leather. It is both strong and sharp. Some quilters use it when sewing through many layers of fabrics, especially high thread count batiks.
This needle comes in sizes 10/70 through 18/110. Choose the size based on the type of thread being used. The heavier jeans threads work best with the larger needle.
