There's a very sort of technical way that you might use a grid, and that's actually to be able to transpose an image from to another place. I've gone ahead and gridded this image into equal increments, you know it's just your basic checker board grid. I have drawn the same grid over here. I like this picture, you know I like the way the road winds through. So I want to repeat that over here, and you know putting it on Xerox paper I'm going to have the wrong kind of paper. So I want to put it on something that I want to work on. So I've put a grid over here, it has the same this can be any size. You can use this to enlarge too. All you need to do is make sure that you have the same amount of divisions, so and that you could make these two inch squares and get bigger. Just so long as you end up having one, two, three, four, five six, seven, eight, nine squares on your page. And how you do this is you come up here and you say, okay where’s my road? Okay my road starts up here, and this is here's the first row, here's the second row. One, two, three, four. It starts between the fourth and the fifth. So one, two, three, four, here's four and five. Now you look at it and it’s kind of, it's right here. So it’s a little bit more than half way up the grid. So one, two, three four, and we've got a little bit more than half way up. So I'm going to start my road here. Now kind it kind of zigs over here and then it zigs back and it's still on the same square the next time we see it. And then it comes over into this square over here. And that's pretty much where we lose it at this point. For this part of it. So I found my road there, now we find it again over here. It's now in the next square, and it's one, two, it starts in the third square here. It starts about half way up the square, and it comes to about here in the next square.
