I will just have to go with the flow when it comes to the numbers.
Now...the following may be in the instructions somewhere on in a video, but I have observed a variation between the Warm & Cool Block 1 (and the full list of fabric in the Introduction file). The Warm quilt includes a "value" description (light, medium, dark etc) for each fabric "#". The Cool quilt does not. That is OK but the paper pattern also has the value for each fabric # and it is the same for both Warm and Cool. So, when looking at the Cool quilt, it is obvious to me that the center of Block 1 should be dark but light is on the foundation.
It is neat that Becky changed up and provides two colorways. I just think, since she is providing separate instructions for both colorways, the Cool quilt foundation should either have the correct value or be removed completely from the foundation.
