They look really complicated, but they are not - I promise:) You need a pretty simple template made with two squares, then you just stamp, rotate cardstock, and repeat.... then voila! Instant coolness! Let me give you a piece of advice, don't spend money buying a template, you can just make your own.
For the first one I made, I used square framelits. That took any measuring out of the equation and sped up the process. I made a few with that template, then I decided I needed a bigger one. It was not hard to cut a square, trace and cut out the center on my Stampin' Trimmer. When it came time to stamp, my Stamparatus made things super simple. You can make a template out of plastic, or just use cardstock like I did. Take a look at my samples below, then see three videos that I watched to get me started.
