Do what you have to to get it to your Gran asap. She is going to love it no matter what, she already loves you.
We are not promised tomorrow, just saying. My Granny always make us quilt tops so when I make her the first quilt she every got from anyone it wasn't perfect, but it was made out of farm animal blocks she had given me, i made them into log cabin blocks using the animals as the centers and it was a quilt as you go and one of my first quilts, she loved and and slept with it all the time it was about 13 years before she passed and I now have it, but she was proud that I became a full quilter and she got to see my longarm and all before she passed. I did my first potholder quilted and all on her treadle.
