Just poke around and mess with it. It can be a lot of fun, both to create and to see what others have created. My kids and I have enjoyed this for more than a year.
"I pledge allegiance to the flag of the United States of America, and to the republic for which it stands, one nation under God, indivisible, with liberty and justice for all."
Very cool... I made one that looked like a spider web... but some of them are exquisite!
just keep goofing around, you'll discover the exquisite ones are really not that hard to make :)
