Good luck quilting a Grandma's Flower Garden. One thing you could consider doing is having the quilt basted by a long arm quilter. That way the sandwich is already made for you and will make the quilting easer. I have one that I only have the last row of flowers to put on and then some border pieces and then it will be ready to quilt. A few years ago I did a lot of hand quilting and I think even with experience it will be difficult for me.
