Finish the quilt as you intended. It was a thoughtful gift on your part to give.
Yes, most people have no idea the amount of time and labor that goes into a quilt, let alone the cost.
I recently gave a quilt to someone who had been in a car accident, survived but had serious injuries. She loved
the quilt and I think it has comforted her during a needed time of caring. I rarely give quilts away other than baby quilts or a special need I see.
