Here is a recent purchase. I have a special interest in this pattern, the Sanderson Star, so was pleased to acquire this quilt at a reasonable price.
It is also not square. Beds changed shape during the 20th century, and quilts became rectangular in shape to fit the new-sized beds. In this pattern, which was very popular, the centre stayed the same but the borders in one direction were enlarged to create a rectangular quilt. When I get a chance to measure, I will confirm this.
The quilt came from an established dealer in the North East who has her own collection of quilts. No further information on this quilt.
