2. We'll need some thin yellow lines. You can draw them, but here I'm going to use the "Grass 2" shape, making it tall and thin. Don't make it too tall, as we'll be stretching it out upwards. Simplify the shape if you're using that method.
3. Using the color picker, make orange your foreground color. Rasterize the shape by holding CTRL and clicking the thumbnail in the layers palatte. Now go to Edit>Stroke (Outline) Selection. Make sure orange is the color in the dialogue box, and "Inside" is selected under Location. Choose an appropriate width. I'm using just 1 px here. Click OK.
If you can't see the orange or it's blocking out too much of the yellow, just undo the action (CTRL-Z), adjust the width, and do it again.
One of these layers is simply a backup in case you decide to trash a layer and start over. Since we'll work only one at a time, only one needs to be visible.
5. With the visible layer, go to Filter>Distort>Liquify. Go over each of your lines with the Warp Tool (top of the tools on the left--looks like a hand finger-painting). Go over each or the lines a few times giving each a little bit of wiggle. I used a brush size of 20 (diameter should be a little more than the thickness of the lines) and brush pressure of 100. Click OK. It should look something like this:
6. Now take the smudge tool and start bluring the liquified lines, first going in short upwards strokes, then gently smudging them out to the sides. I'm using a soft-edged brush at 20 px and 10% strength. (I recommend making a copy of this layer first. It's very easy to use more smudge strokes than you can undo, and if you'd like to start over, you won't have to re-do the liquify step as well).
Oh, and one more nifty tidbit I discovered: When you want to undo a long series of actions (like a series of smudge strokes), you don't have to do CTRL-Z for every one. Just hold down CTRL and hit Z repeatedly as fast as you like. Nice little time (and irritation) saver.
Now get out that list of drawing ideas and set something on fire!
