This pattern is called ‘improved nine patch’. A lady in one of the nursing homes I worked at, had made one and I was very impressed with the design.
I did not make this one completely, it was partially finished and it is vintage fabric. When I came upon it, I could not resist. I did finish it, and learned a lot about doing curved seams. It is small, about 45 inches square, so will be a lap robe to snuggle under when DH turns the air conditioning up too cool to suit me, and this fall when it’s too warm for heat and too cool for comfort. I plan to hand quilt it.
