This is another fun stitch you can use to fill larger areas. Bring your needle up at 1 and down at 2, leaving some thread slack across the surface of the fabric. Bring your needle up at 3 to catch the loose thread and then back down at 4, just below 3 to catch the loose thread under a small stitch and pull the thread through creating a V-shaped stitch. You can also make longer tails for your flies (5). You can place any number of these stitches randomly over an area of fabric, build them into a line resembling foliage, or offset the stitches to create more of a zig-zag pattern.
Never heard of fly stitch before, thank you for teaching me something new! X
