Straight needles are long, slender tools used in knitting and sewing. They typically have a pointed end for piercing fabric and a rounded end for holding yarn or thread. Straight needles come in various sizes and materials, such as metal, plastic, or wood, allowing crafters to choose based on their preferences and project requirements. In knitting, straight needles are often used for creating flat pieces of fabric, like scarves or blankets. They are available in pairs, with each needle used to hold stitches while the other is used to knit. Many knitters also use straight needles in combination with other tools, such as circular needles or double-pointed needles, for more complex projects.
