Simple lines: These are great for outlining shapes or creating borders. You can use a single strand of thread or multiple strands for a thicker line. Dashed lines: These are created by making a series of short chain stitches. They can be used to create a variety of effects, such as lightning bolts, raindrops, or waves. Curvy lines: These are created by making chain stitches that curve in a particular direction. They can be used to create flowers, vines, or other organic shapes.
