I first used/designed these about a year ago in my Project Life 2012 | Week 13 spread (click on the images below to go to the original post):
Here's a video tutorial that walks you through the steps of tracing and cutting these journal cards:
This image is included in the video above and shows how different settings and paper impacted the cuts. The top two rows were using Bazzill textured orange peel cardstock and the bottom row was a non-textured cardstock (that seemed to work the best with this particular design).
I've also got two more sets of these journal cards coming out on Friday from Designer Digitals.
