I also attempted to cut out the shapes, but since you can't really change their shape or slightly move the letters around to make them fit together, it wasn't very helpful.
I have also tried using the computer (PowerPoint, if you must know, as my Photoshop skills are nil) to make the shapes. They are much cleaner, but lack the rough, artistic look of the hand-drawn characters. This one says "Gary." I hope :)
So here are my first to basic attempts at writing full sentences in Gallifreyan. This says "Give me liberty or give me death" (more or less).
And this one says "If you wish to make an apple pie from scratch, you must first, invent the universe." Also more or less.
I highly recommend learning it. The alphabet/code is an easy learn and there are lots of resources online (http://timeturners.wikidot.com/circular-gallifreyan). And it looks cool. At very least, all you Whovians should figure out how to write your name!
