First let's set up the Pencil Tool (FreeHand Tool). As you can see above, I set it up to draw using the Calligraphic pen option. You can set up the options as you see fit, for your own drawings. The point here is to be as random as possible, because as we all know, no two snowflakes are the same.

Next, draw a single, strange path like shown above. Again, just do something random, it will all come together in the next step. Give it a solid fill color so you can see the final results a little better.

Now we need to setup the Mirror Tool. This is not to be confused with the Reflect Tool in the main toolbar. The Mirror Tool is found in the Xtras Tools Toolbar as shown above. Just double-click on the tool to bring up the options.

Here, set the mode to Multiple, using the Reflect option. Enter in a value for the number of times the shape will be copied. I recommend values under 10, as it may get too complex.

When you go back to your drawing, click and drag around the page. You'll see the Mirror tool in action as shown in the animation above. As you can see, it really starts to look like a snowflake no matter where you drag it. You can get a ton of different flakes from that one shape alone. Very cool!

When you get a shape you like, just let go of the mouse. While the shapes are all still selected, use the Join command found under the Modify menu.

When you Join the shapes together, any overlapping areas will be automatically punched out so they are transparent.

After you create a nice series of snowflakes, give them some good icy cold colors. You can even use Lens fills to create different levels of opacity later when you add them to your art.

Add them to a new Graphic Hose and spray them around, adjust the colors as needed depending on what color background you are going to use. How easy was that?!
