I know that the general idea is that each of the rounds of circles is made in three steps. First you make a really long chain. Second, one half of all the circles are made into this chain and they are connected to the rest of the blanket (you can see this in the second photo). Third, there is another row that makes the second half of all the circles.
I know the pattern was on a blog or personal website of some kind, and there were step-by-step pictures there to explain it not just a written pattern. I know that I can mostly figure it out on my own, but I don't remember the math to figure out how long to make the chain for the next row. I can unravel the last completed round, but I would rather not if I don't have to since it's pretty large at this point. I just want to see if anyone knows what I am talking about or where on the internet this pattern could be. It's also been a few years, so if anyone knows what I'm talking about and knows it isn't out there anymore that would be useful info too.
Thanks so much guys!
