This is done in Mosaic Crochet. The pattern is fully written out for every round, and a chart is included. There are also pages formatted for printing out the chart if desired. Please contact me with errors or questions. My final throw ended up being 46” square, but hook size, or yarn can make this number vary. Link of the pattern is below!
