The Mrs. Keller's Nine Patch quilt block is an old favourite of quilters. Depending on your colour choices, you might have to search for the nine patch as here, it is discretly hidden in the block centre (due to fabric choices).

Both of the quilt layouts illustrated below use an on point setting of the blocks. The quilt layout on the left adds extra splashes of colour in the form of blank blocks along the setting triangles along the edges. The quilt layout on the right adds corner triangles to each block, to increase their size and adds sashing strips to give the appearance of peeking through a window at the design.
