Have you ever wondered how to create an Easel Card? Here's a video from Stampin' Up! to show you what you need to know.
Pretty simple, isn't it?! You can alter the measurements to fit any size card you want. The important thing is to make your card base twice as long as the finished card.
For the end of the base that folds, I usually make the score line at the halfway mark, but in the video Brian shows a score line a little lower than that. Both will work, but if you're trying to figure out measurements for a different sized card, the halfway mark may be easier to figure out.
I hope you'll try one of your own, now that you've seen this video on How to Create an Easel Card.
