And by lid, I mean **hat** :)
Incorporate a hat into your card - whether it be a stamp or patterned paper (or anything else you can think of), just make sure it has a hat on it.

Even though tomorrow is our last day of Paper Popsicles Week, you will still have until Sunday at 11:59 PM EST to get your cards linked up. If you're like me, you get a lot of scrapping done over the weekend, so I hope this gives you all the time you need to catch up.
