Need Help with Quilt Backing
Is there a formula regarding how much fabric is needed for quilt backings? My brain just isn't working right to figure this out. I apologize in advance. I have a top that is approximately 86X86. I am trying to figure out how many yards I need to use for a backing for it. I found 3 yds of 42 inch fabric I would like to use but I cannot figure #1 if I have enough fabric, and #2 how to cut it and piece it together to make it. Any help is appreciated and even maybe point me in the right direction to find out how to do this.
