As I sat at my son’s football game one Saturday morning I saw a woman with a hat similar to this. I loved it and as soon as I got home I grabbed my yarn and hook and came up with the Diamond Trellis hat pattern.

If you would like a more detailed pattern with lots of photos and much better instructions - Please see my full version - Diamond Trellis Hat. But for those who know the basics of hat making and are willing to figure things out, here is a quick free version.

It is pretty quick and easy, but I would say this pattern is a medium difficulty level for those with experience in a variety of stitches. You do need to know how to do sc, dc, hdc, hdc in the 3rd loop, fpdc, bpdc, FPtr2tog.
