Use the words from a song to create a border. 

Party Stickers from Frances Meyer

A good example of using 8.5x11 paper to fill a 12x12 page. Simply turn the paper at an angle, trim, and back with a coordinating paper. (In this case, several different solids.)

Fast and easy with the circle cutter. Lots of little details around each picture, including little hand-drawn roses, dots, X's, and squiggles to give the page interest.
