Here is another example of a quilt using a variable star, this time combined with other blocks. It's a miniature medallion quilt (27" x 27") with a Christmas theme, made as a progressive quilt for Quilt Nebraska 1999. Does anyone from Nebraska recognize their block?
The variable star nicely unifies the wide variety of star-center block choices. And the way they are lined up, they give the illusion of Square-in-a-Square blocks between them. Have you used this block in any other interesting ways?
