First cut your paper to 4.25x11
Fold it in half
Get you die cut and place it on your card stock with the top edge above the fold. I put this one a little further than necessary because of the hole on the tag but normally you can just barely have the top above the fold.
Run your die and paper through your cutting machine. You may have to run it through a couple of times because it is thicker.
Now you have a shaped card base to make your card with! It will work with most shapes so the possibilities are endless!!
