I also made this coordinating box in a bag with the Shades of Spring DSP. It's also super easy and fun to make. Here is the tutorial.
I have also created a video tutorial to show you how to make the easel card!
I scored both strips at 1/2" and then cut every 1/2" or so so that I could create the bends in the top of the heart. I created a tab at the ends of the 12" strip to join the two strips together. I used sticky strip to adhere everything to the heart.
Then I cut out a heart to place inside to cover up the tabs. To decorate the top, I punched out some flowers and added some buttons, felt flowers and an epoxy brad for the centers. I used the large oval punch to create the leaves and tied some ribbon to connect the hearts together.
