Here's how to prepare an Easter basket on the run. Purchase a deep pre-decorated gift box (you can also use a gift bag). You can find there at dollar tree, Target, or Walmart. You'll also need clear cellophane wrap, tissue paper, and ribbon. All of these can be purchased at the above stores and packed flat.
To create the basket pop the box open and press the top flap into the box. Crumble the tissue paper to create the grass. Fill with Easter treats. Wrap cellophane around the box and secure with a box.
