John Deere Suggestion

Here's one way you could layout the J.D. quilt based on the Lime Squares design. Since the blocks are 12" square finished (12.5 raw edges as per directions) the finished area shown here is 48" x 72". If you want it bigger you can then add one or more borders. If you want it smaller, leave off a row of blocks.

Let me know what you think. The color placement here is only a suggestion. Doing "random" is one of the hardest things to do in the program and for me anyhow. So put yours where you want.
