What a beautiful old Grandmother's Flower Garden quilt! Lucky you!! Going only by the green and yellow, I'm going with the 40's. I don't think it's much older than that, but I could be wrong. Photo colors can be tricky! Reds are a bit easier to pin down, but still... those greens were mostly in the 40's if I'm seeing what I think I am. Gorgeous find! Glad your family kept them intact for you!
