With a guild I belonged to years ago, it was very simple. It was done in red, white and blue. Muslim is what was used for the white space. Then the cornors were done in blue, with red rectangles between. Each new member was given a little package with the material in it and had to sew their own. Very cute and easy. The total rectangle was about 3x4. Saftey pin on the back was used to attach it to your top.
