I promise you this will be the easiest DIY project you'll ever do. It's literally just one step, but I think the results are quite pretty for the amount of work it takes. :)
decorative paper punch
decorative paper (I used gold vellum)
The punch I used is this floral one from Martha Stewart. You can find it at Michaels or anywhere they carry Martha Stewart craft products.
Step 1: Line up the punch with a corner of your paper. Move the paper around to see where it would make the prettiest punch. And then punch! Repeat for all four sides.
And that's it! I told you it was easy.
