This die cut sheet from On the Sunny Side is a case in point. Look at all those fun summer icons.
You can use the die cuts as is or you can doctor them up. I used the ice cream truck (upper L) for my card and altered it by adding brad wheels and a layered sticker with ice cream icons. I used foam tape underneath to give it dimension on the card.
For the card base, I used a folded card from Memory Box. Love those. There you have it. A quick and easy summer card.
I hope you have a great day. Me? I'm off in search of ice cream.....
