This is not strictly a die-cut box, but it's made from the Top Note die. I made one at an SU downline event that I attended. It was a little too small for a gift card. So I played around and tweaked the measurements. It's pretty easy to put together with some simple scoring. Here's a link to the
tutorial.
I made several as I got on a kick with these, you can find several examples if you poke around a bit (or check the Big Shot category). Make them with chipboard for a masculine look, too!
