Both of the quilts posted are lovely. Katier825's is striking because it uses the setting triangles and corners to carry out a single visual concept. One of the visual 'attractions' of of your DP9 is the use of the conversation print and you might want to think of its overall impact. Using the same setting triangles and corners would be really striking. You might consider using gray for your sashing and perhaps the red in a small border surrounding the body of your quilt or you could use the red in a piping combined with your binding-depending on the binding you chose. Red piping with one of the blacks for binding would be striking.
