Stencil issues

I'm trying to stencil this grassy area onto my age, since I'm makin' a beachy kinda island. The only problem is its only covering one small little area of it, instead of a huge patch, that I'm aiming for.

Also a suggestions for the authors of the tutorials. I love how direct everything is, but please explain the why, not the how. Most of them say, do this, do this, do this and you'll have a stencil. Instead of do this, because what this does is blah blah blah, it would just make things alot easier to understand what I'm doing, instead of just doing it.
