Starting with the outer pink or red row, begin by laying out your paint chip circles into two rows overlapping the circles as you go to create a 6' wide arch. You will want to make sure you have a large work space to work on so that you can layout the entire 6' wide rainbow in one piece.

Be sure to adjust the rainbow as needed to get a good arch and then finish taping all of the paint chip circles into place. Once complete, use thumb tacks or wall mounting strips to attach the rainbow to the wall behind your dessert table or as a photo booth backdrop.
