Embroidery needles are specialized sewing tools designed for hand or machine embroidery. They typically have a larger eye to accommodate multiple strands of thread, making it easier to create intricate designs. The needle's sharp point allows for smooth penetration through fabric, ensuring clean stitches. These needles come in various sizes and types, each suited for different fabrics and thread weights. For example, ballpoint needles are ideal for knit fabrics, while sharp needles work best on woven materials. Choosing the right embroidery needle is essential for achieving the desired results in your stitching projects.
