Let me tell you what I did. I had a large quilt top that needed mitered borders. I made a quarter square triangle big enough to lay the quilt top on top of with the size of the border needed extra. I glue basted the quilt top edges under and then stitched in place. I squared it all up and had instant mitered borders. I left the excess fabric behind the quilt as I wanted to add trapunto but it could be cut out and reused. I wanted easy and fast with accurate results. Not many will understand using that much fabric but that's just the way I am. I have fabric and I'm not afraid of using it. LOL
