I just made a quilt using the turning twenty like pattern using only three pieces to make the block.(12.5x12.5) I used the large part for the theme and the two other parts for companion fabrics and it turned our really well. I used some novelty Alabama fabric for the large piece , a red (dominate) poka dot and white for one piece and a black and white (dominate) poka dot for the other. Going to bind with another black (dominate) and white. Now I am rambling but hope you get the picture!
When I get it finished, I will take a picture and try to post. I have not done that before.
Good luck.
