Monica33's blog is very helpful, thanks Monica.
After reading a couple of the other TQS BOM pages, I found some end measurements for each 'round' in the first month. I then realized that even though my printer was set for scaling to none, the end center circle was only 11 inches unfinished instead of 11 1/2. I measured the grid and thought it was 2" like it was supposed to be. But I printed the template on my office laser printer and it gave me the results I need, I think. I'm going to redo the center. I do think that if they would add the size we should expect to see at the end of each round, it would be easier to double check our work. I'm used to 'resewing', I don't mind. I'm using stonehedge fabrics and they look sooo good.
