So I am new. Let's just remember that this is my very first project...

I did the jelly roll race. Added a 1.5 inch stop border. And a 6 inch second border.

Now I just measured my quilt so I could start to figure out the backing size needed. My top and bottom are measuring about 63" and 65". My sides are about 76" and 78 ".

I'm off two inches!

What now? Do I need to take it all apart and try again? Or just quilt it and then square it up? I'm so lost. And I thought I was doing so well
