Needle techniques refer to various methods used in sewing, embroidery, and other textile arts that involve the use of a needle. These techniques can include basic stitches like the straight stitch and zigzag stitch, as well as more complex methods such as cross-stitch and sashiko. Each technique serves different purposes, from simple repairs to intricate designs. In addition to sewing, needle techniques are also prominent in medical practices, such as acupuncture and injections. In these contexts, needles are used to deliver medications or stimulate specific points on the body. Mastery of needle techniques is essential for both artisans and healthcare professionals to ensure precision and effectiveness.
