Step 1: Using a dark red lip liner, map up where you want your stitches to be. Once you get the shape you want, deep the lines up. Step 2: Draw a line on each side of the stitches, leaving some space between the lines. Then blend the outer lines using a pencil brush. This step will make your stitches look three-dimensional and real. Step 3: With a white pencil or eye shadow, highlight the inner stitches to make them look deeper.
