As long as you understand your layers, you can do this. Basically all it means is that you can make one layer (usually a paper) take on the form of another layer (usually a specific shape). Clear as mud? Let's say I have this:
A simple orange star, with a stamped effect:

But for whatever reason you like this pattern paper:
{paper from Aja Abney's "My Wish For You" kit}
You can "clip" them together to create this:
To do this, put your star (or whatever it might be) and your paper onto your canvas. You must make sure that the star (or layer you want your paper to be "clipped" to) is just below the paper. Then click on your paper layer (above the star). Simply press Ctrl+G and voila!
Alternatively, you could also go to the top of your screen and click Layer>Group With Previous to achieve the same results.
Here's a layout I recently did where I used this technique in a couple of different ways.
It's a two page layout, you can see them a little better separated:
So, clipping masks. First of all, I used this little circle frame:

As you can tell, I duplicated it several times and arranged them around my page, then selected various solid colored papers and clipped them to the frames. I also used clipping masks to create the title for my page. I started with this clear alpha with white painted edges:

Again, I just took a few of the same solid colored papers and clipped them to my different letters. Since this was a clear element, it only took on the parts that were white, which I think is a pretty fun look.
Anyway, these are just a few examples of some fun ways to use clipping masks. Like I said, it is super easy and you can some very fun effects with it! If you try it I'd love to see the results!
