Glue two square sheets of scrapbook paper together. Use one patterned and one solid color.
Turn it over to the colored and patterned side is facing the surface you are folding it on. Fold in half vertically unfold.
Take one corner and fold it into the centerfold, repeat with opposite corner. Take the straight line of the fold you have just made and fold it again to the centerfold. Repeat with the other side.
Fold in half vertically again with the colored and patterned side on the inside of your fold. Fold each half down creating a fold line parallel to the vertical fold.
Now you have a plane! Decorate it any way you like with additional scraps of paper.
