Here's how I did it!
I followed Tim's instructions up until the point where you have to die cut the corrugated cardboard. At that point I matched my tag up with the tag-shaped corrugated cardboard and slipped in into the embossing folder.
I lined up the embossing folder image with my already embossed tag and then pulled out the tag leaving the cardboard in place.
I ran the folder through my big shot and embossed the design onto the cardboard.
Then I used an exacto knife to cut out the leaf shapes.
It doesn't quite match up perfectly but it's good enough for me! At this point I followed the rest of Tim's steps. I used a different walnut stain spray and bronze Perfect Pearls mist since I also don't have the distress stain sprays. Here's the end result!
