Yes, I was able to figure out the pattern by drawing it out on graph paper. I contacted Laundry Basket Quilts when I first saw it (before I realized that it was first posted in 2014, lol); they have not responded yet so I am guessing I will have to just make it, and give it a name for my label. Not sure you could use a jelly roll, though. The squares could be whatever size you want them to be, I guess, but the triangles in the corners ( at least, on my graph) need to be a little bit larger, to account for proper setting. I have plenty of fat quarters, though, so I will be using those
