The two constants in this quilt are the beige fabric surrounding the center block, and the small burgundy square in the corners where the sashing intersects.
Starting with a 5"x5" square , this quilt uses 35 center squares plus three more fabrics, complete with jelly roll sashing and three borders to finish at 62"x74".
You can build it bigger by adding one or more frames around the center square or by making more rows of blocks.
