The back stitch is a fundamental embroidery technique for forming unbroken lines. To execute a back stitch:
1. Preparation: Pass the needle upwards through the fabric at the starting point of your desired line.
2. First Stitch: Insert the needle back into the fabric slightly behind the initial entry point. This forms the initial small stitch.
3. Subsequent Stitch: Bring the needle up at the termination point of the preceding stitch. Then, insert it slightly behind to create the next stitch.
4. Repetition: Continue this procedure, ensuring consistent spacing and alignment of stitches to maintain a continuous line.
The completed embroidery will exhibit a sequence of uniform, flowing stitches forming a straight line, thereby providing a precise and distinct outline.
