I did it! Here's the last barn raising square. I counted all of the squares 3 times before I came up with 42. I was a bit scared because I thought that I was finished, then when I had the wrong number. I counted again. 42. Then 42 again.
As we speak, the last 6 are downstairs being blocked. Now, all I have to do is set them out in the order that is somewhat pleasing, sew them all together and stitch around the outside. Have I said this before? I feel like I am repeating myself. Sorry if I am.
