Beach Towel/Blanket

We would like to create a beach towel that has corner pockets on all 4 corners, so you can stick sand in them, so the blanket does not fly away. I would like to see a picture of the towel and pockets with dimensions before I commit to something. The corner pocket is basically just a triangular piece of material over all 4 corners. I am looking to just have a couple made at first, and then I would like to have more made after I use the first one to create advertising pictures and videos.
