Did you hand or machine quilt? I really can't tell from the photos.
The reason I ask is that I completed the piecing on a GMFG last year. Since I did all that hand piecing it seems like I should also hand quilt. But, I'm not a good hand quilter, especially through seam allowances. My hexagons are 3/4" so there are a lot of seam allowances!

Oh, my GOODNESS! It's STUNNING!!

Beautiful quilt; beautiful story. Your mother will treasure it. I love your quilting. It's fantastic!

That is just fantastic and oh what a great time you and your sisters must have had!

[ I know this will seem like blasphemy for me to say, but Grandmothers Flower Garden is not one of my favorite designs......HOWEVER the way you quilted yours just blows me away with its' beauty and so now I can say there is one Grandmothers Flower Garden I like.......YOURS!!!!!!!]

I could have written the above. But you and your sisters have come up with an astounding quilt!!! It is beautiful, and is a project that most of us couldn't do, wouldn't do! I have arthritis to the point that I can't do small things (that's my excuse, never mind the lack of skill or of patience). Thank you for sharing this gem with us all. You have broadened many horizons!

this is so beautiful!!!
the great colours and such a gorgeous quilting!!!

It is machine quilted. I am sad I couldn't quilt it by hand- I would not have finished it in this life!

What a great idea for quilting it, thanks for sharing:) It is beautiful.

WOW! This is beautiful and the story behind it is more beautiful! How lovely that you and your sisters worked together on this :)

Oh, Geta....beautiful, beautiful, beautiful!!! Just on the off-chance (hah!) that your Mother won't like it, may I offer my services as a surrogate Mother for all of you? Of course, that would mean the quilt would then revert to me...:) LOL, as I said, just beautiful!
