I really want to stress to you beginners (like me), I have no particular talent for this kind of thing, I'm not artistic, I'm not particularly imaginative, and I can't draw to save my soul. If I can do this, you can do it. Really, work up the nerve, and give it a try. It's easier than you think. Oh yes, be very forgiving of yourself, or you will hate it. Using variegated thread helps too.
