Here is the link that was shared with me by Ajeutsler on how to make the criss-cross card. Now I want to share that with everyone else.

One little tip that I'll pass on since I learned the hard way: if you don't use double-sided patterned paper , you need two 4x5 sheets of paper so that you can cut them in different directions and use half of each. Otherwise, the triangles for the front aren't the right shape. This explanation probably doesn't make sense, but you'll see what I mean when you make one.

I actually made a mock one first using copy paper to make sure that I was doing it right.
