Straight needles are long, slender tools used in sewing and knitting. They typically have a pointed end for piercing fabric and a hole, or eye, at the opposite end for threading yarn or thread. Straight needles come in various sizes and materials, including metal, plastic, and bamboo, catering to different types of projects and preferences. In knitting, straight needles are often used for creating flat pieces of fabric, such as scarves or blankets. They are usually sold in pairs and can vary in length, with longer needles suitable for larger projects. Knitting and sewing enthusiasts often choose straight needles based on their specific needs and the type of material they are working with.
