A friend of mine had made a beautiful crib quilt for her grand daughter and when the GD out grew the crib quilt the DIL liked it so well she asked my friend to just enlarge it rather than make a whole new bigger quilt. I believe we just sewed an extension over the edges to enlarge it. I do not recall that she removed the binding. The extension was backed and finished with batting just as the small quilt had been She was a marvelous quilter and was fortunate to be able to finish it as her DIL asked
