Illustrated below, you will see two sample quilt layouts, both using on point settings of the blocks, but with very different, yet striking results.

The quilt layout featured on the left adds extra large corner triangles to the outer edges of each block. The benefits are that you produce larger blocks, hence fewer to construct, and you can play around with the colour palette of those large triangles to produce a variety of lovely designs.

The quilt layout shown on the right uses a standard diagonal setting of the blocks, separating them with sashing strips. This produces (at least to my eye) a sort of "overall plaid" looking quilt -- one of my favourite looks.
