This has me confused because the way she drew it for her column (drawing at right) it would need to be appliqued, not pieced, since the background is all one piece..
In trying to research this pattern, I found it more common to have the area she shows at the center of each side as being in each corner not on the side. It is also more commonly seen with the arc section pieced like this-
I found one antique quilt that looks like the pattern Nancy shows except the arcs are pieced-
Each block has a name embroidered in the center. Nancy doesn't say anything about names being embroidered but it makes sense since it is called Friendship Knot.
You can download the applique pattern for a 6" inch block here. It can be found in BlockBase as #4045.
