I thought stippling and meandering were hard too when I first started. I would tense up and the stitching looked choppy, then I would continually box myself in an area. For some reason then I really got into swirls. They seemed easy enough if you don't go too fast and leave room to back yourself out of the midlle of it. Wavy lines are easy too. One of my favorites is woodgrain. It's a combo of wavy lines and a swirl (like a tree knot) every so often. Or something Angela Walters calls dot-to-dot. When I do it, I work my way over to a spot with a either wavy line or an arc. Then echo it to fill in an area.
