Wow, I can't believe I am not alone working on hand quilting Grandmother's Flower Garden and I've been using (fell in love with) 1930s fabric! I started my project last Spring 2009, self taught. I use quilt patis from Pati herself. She sells the plastic hexagon templates which are wonderful! I have really been enjoying this project - I know it takes years to do but I will keep going! The quilt patis are well worth the investment and not too costly. Here is Pati's info:

I have ordered two times from Pati and talked to her and she is very helpful too. Please let me know what you decide to do and how things work out for you.
