The pattern is called Thinking Outside the Block, designed by Chloe Anderson of Toadusew (toadusew.com). You can buy the pattern or the full kit with material. I reverse engineered it because it is a variant on the Log Cabin style and I found it easy to modify to what I wanted.It is not difficult (a bit picky when you line up the blocks). I love the black and white but if anyone has done this in other colors, could you post? I want to do another one!!!!
