If your Puffer Hug order is a gift, you will have the ability to select the box "This is a Gift Order" when viewing your cart before you check out.

When you add something to your cart, this panel will automatically come up. To bring up the view-cart side panel, click the shopping bag icon that looks like this    on the top-right of the web page.

Check the "gift order" box, located at the bottom of the page when in the view-cart side panel.
