Hi everyone, looking good! Saw you were talking about the cubes, yes they are in OBWs Encore. I tried to figure them out for the Dog quilt I made and even with Hans's help (he's excellent at maths) it was a nightmare. PLus to get all the different variations, you really need the book. BUT here's a link to the relevant pages, free online!
