I too did a Log Cabin Square inspired by Jan's square. I based it off of the Mason-Dixon Modern Log Cabin baby blanket. Highly altered tho, to make it square and the size I was looking for 12 inches by 12 inches. I learned a couple things on this square, a lesson on gauge (I seem to keep having to relearn this lesson) and one on garter-stitch intarsia (as you'll see up close in the 2nd picture. I didn't do a perfect job, but it sure was fun!
