I make the center and then audition border(s). I always have two....the smaller stop border then the final, unless I feel like more. I have to like the quilt, so I do it my way. I have chosen fabric for borders before I finished the center and absolutely didn't like them when I put the fabric next to the finished center and had to go looking for something else. I layer the borders like I think I will like them and then take a picture with my phone. Looking at it in the smaller version seems to make it clearer in my eyes and mind.
