I have machine quilted a number of grandmother flower garden quilts. They’re turned out fine. One I quilted 1/4” inside each hexagon, one the customer wanted a large loopy flower over each flower and a meandering leafy vine around / through the paths- that one is by far my favorite- turned out beautiful. I’ve done edge to edge designs. I love hand Piecing and have made quite a few hand pieced quilts- my travel projects, not all English Paper Piecing projects. I machine quilt them all.
