I have seen several simplified versions of British flag cushions online, but I'm such a nitpicker that I had to try to make flags with the correct dimensions, which I found here. I drafted my flag in EQ and printed out the pattern for paper piecing . Some of the strips are so narrow, that I couldn't have made the blocks any other way. I used fabric from the Reunion line by Sweetwater, and a linen/cotton-mix for the frame on the front.
this brilliant method. So there you have it: Union Flag (or Union Jack as it is often called) + Reunion fabric = Reunion Jack.
