I kind of want to fold the backing fabric to the front for the border as well, but the internet says that method is not suitable for full size quilts. Does anyone know of any specific reason why? It seems a lot easier than any other binding method. This is the first time I'm going to bind a quilt on my own, without my mum or sewing teacher, and it doesn't have to be absolutely perfect, the top isn't either.
I just took an on-line course on Craftsy that taught exactly what you want to do - use the backing to bind - and they say it's possible on any size quilt. After watching, I agree with them. They even show how to miter the corners.
Look what I found when I went to youtube and searched 'quilt backing as binding' - it's 2 parts and the 2nd part starts shortly after you end the 1st part. Not mitered corners though but for a jeans quilt that would be okay.https://www.youtube.com/watch?v=FqCOPdbPVDg
